At present all partitions are scanned, whether marked bootable or not.
Use only bootable partitions, defaulting to partition 1 if none is
found.

Add a way to run a bootdev hunter to find bootdevs of a certain type. Add
this to the 'bootdev hunt' command. Test for this are added in a later
patch, since a useful test needs some hunters to work with.

Some bootdevs must be enumerated before they appear. For example, USB
bootdevs are not visible until USB is enumerated.
With standard boot this needs to happen automatically, since we only
want to enumerate a bus if it is needed.
Add a way to define bootdev 'hunters' which can be used to hunt for
bootdevs of a given type. Track which ones have been used and add a
command to list them.
Include a clang work-around which seems to be needed.

The code in these functions turns out to often be the same. Add a default
get_bootflow() function and allow the drivers to select it by setting
the method to NULL.
This saves a little code space.

At present MMC uses the bootdev_setup_for_dev() function to set up the
bootdev. This is because MMC only has one block-device child, so does not
need to worry about naming of the bootdev.
However this inconsistency with other bootdevs that use block devices is a
bit annoying. The only real reason for it is to have a name like
'mmc0.bootdev' instead of 'mmc0.blk.bootdev'.
Update bootdev_setup_sibling_blk() to drop '.blk' from the name where it
appears, thus removing the only reason to use the bootdev_setup_for_dev().
Switch MMC over to the subling function.

There is no point in trying to match the alias order for bootdevs, since
build_order() either sorts them by priority, uses the boot_targets
environment variable or the bootdev-order property.
Just use the iterator instead, to simplify the code.

Rather than implement this as its own case in build_order(), process the
boot_targets environment variable in the bootstd_get_bootdev_order()
function. This allows build_order() to be simplified.

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.

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.

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.

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.
