Merge patch series "EFI: ti: Enable EFI capsule updates"

Jonathan Humphreys <j-humphreys@ti.com> says:

Enable on disk capsule updates, which includes defining the firmware
components (tiboot3, spl, u-boot) and enabling processing of raw capsule
updates.

This is enabled for several TI SoC based platforms: AM64, AM62, AM62p,
AM69, BeaglePlay, J7, and BeagleboneAI. The configs to enable this are in a
single base config file. This will make it more scalable to add additional
EFI capsule features (like authentication) across all TI boards that have
capsules enabled.

This series also includes enabling serial flash DFU for AM62 and MMC DFU
for beagleplay.
