drm/i915: Add support for pipe_bpp readout
On CTG+ read out the pipe bpp setting from hardware and fill it into
pipe config. Also check it appropriately.
v2: Don't do the pipe_bpp extraction inside the PCH only code block on
ILK+.
Avoid the PIPECONF read as we already have read it for the
PIPECONF_EANBLE check.
