28a22cd9a4 bootstd: Fix listing boot devices
bootdev_list() uses uclass_*_device_err() to iterate devices.
However, the only value _err adds is returning an error when the device
pointer is null, and that's checked anyway.

Also there is some intent to report errors, and that's what
uclass_*_device_check() is for, use it.

eccb25cd59 bootstd: Allow the bootdev to be optional in bootflows
With global bootmeths we want to scan without a bootdev. Update the logic
to allow this.

Change the bootflow command to show the bootdev only when valid.

a18686cda1 bootstd: Tidy up var naming in bootdev_setup_iter_order()
Avoid using 'count' to mean either a count or an error, since this is
confusing. In fact, the called function never return 0, since that is an
error.

Use 'ret' instead.

201417d700 bootstd: Add the bootdev uclass
A 'bootdev' is a device which can be used to boot an operating system.
It is a child of the media device (e.g. MMC) which handles reading files
from that device, such as a bootflow file.

Add a uclass for bootdev and the various helpers needed to make it
work. Also add a binding file, empty for now.
