Drivers can have private / platform data contained in structs and these
struct definitions are generally kept in header files. In order to
generate build-time devices, dtoc needs to generate code that declares
the data contained in those structs. This generated code must include the
relevant header file, to avoid a build error.
We need a way for dtoc to scan header files for struct definitions. Then,
when it wants to generate code that uses a struct, it can make sure it
includes the correct header file, first.

This does not get a device (struct udevice *) but a struct driver_info *

Signed-off-by: Simon Glass <sjg@chromium.org>
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

With of-platdata, the devicetree is supposed to specify all the devices
in the system. So far this hasn't really mattered since of-platdata still
works correctly.
However, new of-platdata features rely on numbering the devices in a
particular order so that they can be referenced by a single integer. It is
tricky to implement this efficiently when other devices are present in the
build.
To address this, disable use of U_BOOT_DEVICE() when of-platdata is
enabled. This seems acceptable as it is not supposed to be used at all,
except in SPL/TPL, where of-platdata is the recommended approach.

At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.
Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.
Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.

up a device by drive_info index and update the tests to match.

At present the structures are written in name order, but parents have to
be written before their children, so the file does not end up being in

devicetree.
Update the code so that _valid_nodes is in sorted order, by C name of
the structure. This allows us to assign a sequential ordering to each
U_BOOT_DEVICE() declaration.
U-Boot's linker lists are also ordered alphabetically, which means that
the order in the driver_info list will match the order used by dtoc. This
defines an index ('idx') for the U_BOOT_DEVICE declarations. They appear
in alphabetical order, numbered from 0 in _valid_nodes and in the
driver_info linker list.

Currently, binman always runs the compile tools like cc, objcopy, strip,
etc. using their literal name. Instead, this patch makes it use the
target-specific versions by default, derived from the tool-specific
environment variables (CC, OBJCOPY, STRIP, etc.) or from the
CROSS_COMPILE environment variable.
For example, the u-boot-elf etype directly uses 'strip'. Trying to run
the tests with 'CROSS_COMPILE=i686-linux-gnu- binman test' on an arm64
host results in the '097_elf_strip.dts' test to fail as the arm64
version of 'strip' can't understand the format of the x86 ELF file.
This also adjusts some command.Output() calls that caused test errors or
