The current implementation adds this information in the block device's
probe() function, which is called in the blk_probe_or_unbind() in
ide_probe().
It is simpler to do this in ide_probe() itself, since the effect is the
same. This helps to consolidate use of ide_dev_desc[] which we would like
to remove.

The use of atapi_read() was incorrect dropped. Fix this so that it will
be used when needed. Use a udevice for the first argument of atapi_read()
so it is consistent with ide_read().
This requires much of the ATAPI code to be brought out from behind the
existing #ifdef. It will still be removed by the compiler if it is not
needed.
Add an atapi flag to struct blk_desc so the information can be retained.

At present the code does ide_init() as a separate operation, then calls
device_probe() to copy over the information. We can call ide_init() from
probe just as easily.
The only difference is that using 'ide init' twice will do nothing.
However it already fails to copy over the new data in that case, so the
effect is the same. For now, unbind the block devices and remove the IDE
device, which causes the bus to be probed again. Later patches will fix
this up fully, so that all blk_desc data is copied across.
Since ide_reset() is only called from ide_init(), there is no need to init
the ide_dev_desc[] array. This is already done at the end of ide_init() so
drop this code.
The call to uclass_first_device() is now within the probe() function of
the same device, so does nothing. Drop it.

When loading a file from a block device, efiload_read_file
was using the seq_num of the device (e.g "35" of virtio_blk#35)

This cause EFI booting from these devices to fail as an

At present when debugging is off, bootdev_find_in_blk() sometimes fails

Use the -l flag to indicate whether to report missing uclasses.
Also try to be more helpful when no devices are found. For example, when
we see something 'scsi0' requested and nothing was found, this indicates
that there are no SCSI devices, so show a suitable message.
Move messages out of the low-level functions so that silent operation
is possible.
This means they are never reported unless BOOTSTD_FULL is enabled, since
the -l flag cannot otherwise be set.

The current EFI implementation has a strange quirk where it watches
loaded files and uses the last-loaded file to determine the device that
is being booted from.
This is confusing with bootstd, where multiple options may exist. Even
loading a device tree will cause it to go wrong. There is no API for
passing this information, since the only entry into booting an EFI image
is the 'bootefi' command.
To work around this, call efi_set_bootdev() for EFI images, if possible,
just before booting.

OSPI controller supports all types of op variants in STIG mode,
only limitation being that the data payload should be less than
8 bytes when not using memory banks.
STIG mode is more stable for operations that send small data
payload and is more efficient than using DMA for few bytes of
memory accesses. It overcomes the limitation of minimum 4 bytes
read from flash into RAM seen in DAC mode.
Use STIG mode for all read and write operations that require
data input/output of less than 8 bytes from the flash, and thereby
support all four phases, cmd/address/dummy/data, through OSPI STIG.
Also, remove the reorder address chunk in apb_command_write since we now
setup ADDR BIT field that does the same job in a cleaner way.
