Add new SYSRESET_TO_FIRMWARE_UI reset type to allow resetting directly
to firmware UI. This is implemented via the reset command's new -u flag.
For the EFI app, this sets the EFI_OS_INDICATIONS_BOOT_TO_FW_UI bit in
the OsIndications variable before performing a warm reset, causing the
firmware to boot to its setup interface.
