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.
