[U-Boot] [PATCH 1/2] fastboot: more support for reboot-bootloader command

[Steve Rae]

The "fastboot reboot-bootloader" command is defined to
re-enter into fastboot mode after rebooting into the
bootloader.

There is current support for setting the reset flag
via the __weak fb_set_reboot_flag() function.

This commit adds a generic handler to implement code
which could launch fastboot during the boot sequence
via this __weak fb_handle_reboot_flag() function.
The actual handling this reset flag should be implemented
by board/SoC specific code.
