For DP we can use the same PPLL for all active DP
encoders. Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work. Also clean up the code
a bit.
v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
- document functions
- break in main encoder search loop after matching.
no need to keep checking additional encoders.
v4: - same as v3, but re-apply to drm-next as the corner
cases are fixed properly in subsequent patches.

Use the proper struct in the union. That field
has the same offset in every struct, so no functional

Roughly based on how nouveau is handling it. Instead of
adding the bo_va when the address is set add the bo_va
when the handle is opened, but set the address to zero
until userspace tells us where to place it.
This fixes another bunch of problems with glamor.

We use __fls() to find the most significant bit. Using that, the
loop can be avoided. A second trick is to use the behaviour of the
rotate instructions to expand the range of the unsigned int to float
conversion to the full 32 bits in a branchless way.
The routine is now exact up to 2^24. Above that, we truncate which
is equivalent to rounding towards zero.
