The A/B slot is chosen at spl stage and should be kept up to
u-boot stage. Decrease slot retry count will cause slot switch
when the slot only has one chance left.
Set the 'bootloader_verified' flag when current slot is running the last
chance at spl, u-boot will treat the slot as bootable if the
'reserved' flag is set even the retry count exhausted.
Test: Slot not switch during 7 times reboot try.

A/B switch logic will be moved to SPL stage if dual bootloader
feature is enable, in such case, we just need to verify single
slot which is selected in SPL stage.
Test: verify and boot ok for imx8m.
