drm/sun4i: dotclock: Fix clock rate read back calcation
When reading back the divider set in the register, we mask off the
bits that aren't part of the divider. Unfortunately the mask used
here was not converted from the field width.
Fix this by converting the field width to a proper bit mask.
Patch 3d50d4dcb0 exposed the CPU address of DMA-allocated pages as
returned by dma_alloc_coherent because Nouveau on Tegra needed it.
This is not required anymore - as there were no other users for it,
remove it and save some memory for everyone.

We'll want to be able to pass in flags, such as asking for explicit

for flags (which could be extended or reduced later if needed, so
start adding flags from the high bits).
Since anything with the upper bits set would not be a valid pipe-id,
an old userspace would not set any of the upper bits, and an old
kernel would reject it as an invalid pipe-id.
