[Intel-gfx] [PATCH v4] drm/i915: use for_each_pipe loop to assign crtc_mask

[Mahesh Kumar]

This cleanup patch makes changes to use for_each_pipe loop
during bit-mask assignment of allowed crtc with encoder.

changes:
 - use BIT(i) macro instead of (1 << i) (Chris)
changes from V2:
 - use int for consistency (Jani)
changes from V3:
 - instead use enum pipe (Ville)
