Subject: [PATCH] arm/trusted-firmware-a: Add cot-dt2c

Platforms with GENERATE_COT need to either have COT_DESC_IN_DTB set or
use cot-dt2c to generate it.  Add cot-dt2c from trusted-firmware-a
sources and its python dependencies to enable this for those that need
it.

Also, move all the relevant platforms in meta-arm-bsp to use 2.12
