[PATCH v5 21/23] board: sk-am69: Define capsule update firmware info

[Jonathan Humphreys]

Define the firmware components updatable via EFI capsule update, including
defining capsule GUIDs for the various firmware components for the AM69
SK.

TODO: possibly make the struct's sk specific.
TODO: add doc commit (and make sure doc is sk/NOR specific, and add OSIP
boot mode)
TODO: update doc to show sk defconfig when building
