Functions (disable_all_writeback_pipes_for_stream &
dc_enable_stereo & dc_post_update_surfaces_to_stream)
always return true, there is no need to keep the return value.
This change is to make the code a bit more readable.

The pmem driver uses a cached virtual address to access its memory
directly. Because the nvdimm driver is well aware of the special

dimgrey_cavefish has no ASD ucode currently, remove its initialization.
