[PATCH 1/2] Add support for kernel and device tree images stored in a partition

[Maxime Ripard <maxime.ripard@free-electrons.com>]

It is a quite common setup to have a partition with all you need to boot
from the bootloader, ie the kernel image, the device tree blob, etc.

This patch introduces a new "file" location for these two images, which
uses in turn the *_part and the new *_part_type variable specifying the
fs type used by mount.
