Pass the framebuffer size in .16 fixed point coordinates to
drm_rect_rotate() since that's what the source coordinates are as well
at this stage. We used to do this part of the computation in integer
coordinates, but that got changed when moving the computation to
happen in the check phase of the operation. Unfortunately I forgot
to shift up the fb width and height appropriately.

With the bogus size we ended up with some negative fb offset, which when
added to the vma offset caused out scanout to start at an offset earlier
than we inteded. Eg. when testing on my SKL I saw a row of incorrect
tiles at the top of my screen.

On my APL the LSPCON firmware resumes in PCON mode as opposed to the
expected LS mode. It also appears to be in a state where AUX DPCD reads
will succeed but return garbage recovering only after a few hundreds of
milliseconds. After the recovery time DPCD reads will result in the
correct values and things will continue to work. If I2C over AUX is
attempted during this recovery time (implying an AUX write transaction)
the firmware won't recover and will stay in this broken state.

As a workaround check if the firmware is in PCON state after resume and
if so wait until the correct DPCD values are returned. For this we
compare the branch descriptor with the one we cached during init time.
If the firmware was in the LS state, we skip the w/a and continue as
before.

v2:
- Use the DP descriptor value cached in intel_dp. (Jani)
- Get to intel_dp using container_of(), instead of a cached ptr.
  (Shashank)
- Use usleep_range() instead of msleep().
