Add support to load DMC v2.0.2 on DG1
While we're at it, tweak the TGL and RKL firmware size definition to
follow the convention used in previous platforms. Remove obsolete
commenting.

Why GEN12_CSR_MAX_FW_SIZE was replaced by platform size if the size is still
the same for all?
Previous platforms used it per platform rather than gen, so I guess
this is what Matt Atwood intended to do and wrote in the last paragraph
in the commit message.
I think we could go either way... no strong opinion on one vs the other.
