The current way of handling things like EFI bootmgr is a bit odd, since
that bootmeth handles selection of the bootdev itself. VBE needs to work
the same way, so we should support it properly.
Add a flag that indicates that the bootmeth is global, rather than being
invoked on each bootdev. Provide a helper to read a bootflow from the
bootmeth.

At present ofnode only works with a single device tree, for the most part.
This is the control FDT used by U-Boot.
When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.
Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
start-up. Also, we don't need aliases to do fixups in the other FDT. So
make sure that flat tree and live tree processing are consistent in this
area.

The requsted partition disk sector incorrectly has the parition start
sector added in twice for UCLASS_PARTITION devices. The efi_disk_rw_blocks()
routine adds the diskobj->offset to the requested lba. When the device
is a UCLASS_PARTITION, the dev_read() or dev_write() routine is called
which adds part-gpt_part_info.start. This causes I/O to the wrong sector.
Takahiro Akashi suggested removing the offset field from the efi_disk_obj
structure since disk-uclass.c handles the partition start biasing. Device
types other than UCLASS_PARTITION set the diskobj->offset field to zero
which makes the field unnecessary. This change removes the offset field
from the structure and removes all references from the code which is
isolated to the lib/efi_loader/efi_disk.c module.
This change also adds a test for the EFI ReadBlocks() API in the EFI
selftest code. There is already a test for reading a FAT file. The new
test uses ReadBlocks() to read the same "disk" block and compare it to
the data read from the file system API.

Asking if the alias we found actually points at the device tree node
we passed in (in the guise of its offset from blob) can be done simply
by asking if the fdt_path_offset() of the alias' path is identical to
offset.
In fact, the current method suffers from the possibility of false
negatives: dtc does not necessarily emit a phandle property for a node
just because it is referenced in /aliases; it only emits a phandle
property for a node if it is referenced in <angle brackets>
somewhere. So if both the node we passed in and the alias node we're
considering don't have phandles, fdt_get_phandle() returns 0 for both.
Since the proper check is so simple, there's no reason to hide that
behind a config option (and if one really wanted that, it should be
called something else because there's no need to involve phandle in
the check).

Booting from a short-form device path which starts with the first element
being a File Path Media Device Path failed because it doesn't contain
any valid device with simple file system protocol and efi_dp_find_obj()
in efi_load_image_from_path() will return NULL.
For instance,

With this patch applied, all the media devices with simple file system
protocol are enumerated and the boot manager attempts to boot temporarily
generated device paths one-by-one.
This new implementation is still a bit incompatible with the UEFI
specification in terms of:
* not creating real boot options
* not try
"If a device does not support the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, but
supports the EFI_BLOCK_IO_PROTOCOL protocol, then the EFI Boot Service
ConnectController must be called for this device with DriverImageHandle
and RemainingDevicePath set to NULL and the Recursive flag is set to TRUE."

Under the current implementation, booting from removable media using
a architecture-specific default image name, say BOOTAA64.EFI, is
supported only in distro_bootcmd script. See the commit 74522c898b
("efi_loader: Add distro boot script for removable media").
This is, however, half-baked implementation because
1) UEFI specification requires this feature to be implemented as part
of Boot Manager's responsibility:
3 - Boot Manager
3.5.1 Boot via the Simple File Protocol
When booting via the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, the FilePath will
start with a device path that points to the device that implements the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or the EFI_BLOCK_IO_PROTOCOL. The next
part of the FilePath may point to the file name, including
subdirectories, which contain the bootable image. If the file name is
a null device path, the file name must be generated from the rules
defined below.
...
3.5.1.1 Removable Media Boot Behavior
To generate a file name when none is present in the FilePath, the
firmware must append a default file name in the form
\EFI\BOOT\BOOT{machine type short-name}.EFI ...
2) So (1) entails the hehavior that the user's preference of boot media
order should be determined by Boot#### and BootOrder variables.
With this patch, the semantics mentioned above is fully implemented.
For example, if you want to boot the system from USB and SCSI in this
order,
* define Boot0001 which contains only a device path to the USB device
(without any file path/name)
* define Boot0002 which contains only a device path to the SCSI device,
and
* set BootOrder to Boot0001:Boot0002
To avoid build error for sandbox, default file name "BOOTSANDBOX.efi"
is defined even if it is out of scope of UEFI specification.
