[PATCH v1 2/2] bootdev: scan boot devices at each priority level

[dmukhin at ford.com]

From: Denis Mukhin <dmukhin at ford.com> 

Currently, default 'bootflow scan -lb' will stop booting the board
if any of high-level priority bootdevs cannot be hunted even if there
are bootdevs of lower priority.

For example, if board has both NVMe (priority 4) and USB MSD devices
(priority 5), and if NVMe bootdev hunt fails (in an event of bad NVMe
firmware update), USB (may be recovery bootdev) is never hunted
automatically, leaving the board in U-Boot prompt (user intervention
is needed, e.g. something like 'bootflow scan usb' to hunt USB).

Fix bootdev_next_prio() to scan bootdevs at the lower priority level
by not exiting the scan loop early.
