Now that we can expose boot for UBI partition on MTD devices (NOR and NAND).
This patch adds the distro script to automatically payloads from UBI volume called boot detected in a bootable partition in GPT partition in the MTD device.
example to start from nor0 and nand0:
func(EFIMTD, nor, 0) \ func(EFIMTD, nand, 0)
