[PATCH v5 4/7] mach-snapdragon: enter fastboot on bootloader reboot reason

[Aswin Murugan]

Update preboot to check the reboot-mode environment variable
and automatically enter fastboot mode when the reboot reason
is "bootloader". This enables 'adb reboot bootloader'
functionality on Qualcomm platforms.

The reboot-mode variable is set by the reboot-mode uclass
via EVT_LAST_STAGE_INIT before preboot runs.
