This patch add DSC block and sub block to support new DSC v1.2 hardware
encoder. Also sc7280 DSC related hardware information are added to allow
sc7280 DSC feature be enabled at sc7280 platform.

You're not adding support (that happened in previous patches), you're
only describing SC7280 DSC blocks.  Drop the first sentence.

This should go in a separate Fixes: patch.

Not sure if HW_ is necessary here, DSC_BLK_1_1 seems cleaner.

Bit scary that the blocks have the same address, because it is purely
driven by the sub-blocks with non-overlapping offsets/ranges.  Should we
clarify that with a comment?

While at it, in v1.1 we use a hacky DSC_CTL() macro to bind a pingpong
block via a register in this magical "CTL" range at (0x1800 - 0x3FC * (m
- DSC_0)), can and/or should we represent that CTL sub-block explicitly
in the catalog for v1.1 hardware as well?
