Replace occurrences of "v & 0xffffffff" with lower_32_bits(v)
when it's next to an upper_32_bits(v). Also remove unnecessary
"upper_32_bits(v) & 0xffffffff" code snippets.

It seems this got dropped when we merged UVD support
last year.  Add this back now.

Our different hardware blocks are actually completely
separated, so it doesn't make much sense any more to
structure the code by pure chipset generations.

Start restructuring the code by separating our the UVD block.

v2: updated commit message
v3: rebased and restructurized start/stop functions for kv dpm.
