drm/i915/bdw: Broadwell has PIPEMISC
And it inherits some bits from the previous TRANS_CONF (aka PIPE_CONF
on previous gens).
v2: Rebase on to of the pipe config bpp handling rework.
v3: Rebased on top of the pipe_config->dither refactoring.
v4: Drop the read-modify-write cycle for PIPEMISC, similarly to how we
now also build up PIPECONF completely ourselves - keeping around
random stuff set by the BIOS just isn't a good idea. I've checked BDW
BSpec and we already set all relevant bits.
