drm/i915: Eliminate bigjoiner boolean

Browse Source 
Since we now have the bigjoiner_pipes bitmask the boolean
is redundant. Get rid of it.

Also, populating bigjoiner_pipes already during
encoder->compute_config() allows us to use it much earlier
during the state calculation as well. The initial aim is
to use it in intel_crtc_compute_config().

v2: Move the hweight(bigjoiner_pipes) stuff to a later patch
