Subject: drm/i915: Enable non-contiguous pipe fusing

Git-commit: 0a7ada196675717b1c9290aa325f054f300f696b
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
As we have already enabled supported infrastructure for
non-contiguous pipe fusing in driver, we don't require non-contiguous
pipe_mask check anymore.
It is an unlike condition, it make sense to remove this condition.
changes since RFC:
- using intel_pipe_mask_is_valid() function to check integrity of
pipe_mask. [Ville]
v2:
- simplify condition in intel_pipe_mask_is_valid(). [Ville]
v3:
- removed non-contiguous pipe fusing check. [Lucas]
