ti: k3: Introduce lite device board support
Add device support for the 'lite' K3 devices. These will use modified
device addresses and allow for fewer cores to save memory.
Note: This family of devices are characterized by a single cluster
of ARMv8 processor upto a max of 4 processors and lack of a level 3
cache.
The first generation of this family is introduced with AM642.
See AM64X Technical Reference Manual (SPRUIM2, Nov 2020)
