drm/i915: Silence __iomem sparse warn

We don't care about __iomem mismatch when dealing with error
pointers. Silence it with ERR_CAST().

drivers/gpu/drm/i915/display/intel_dpt.c:136:21: warning: incorrect type in assignment (different address spaces)
drivers/gpu/drm/i915/display/intel_dpt.c:136:21: expected struct i915_vma *[assigned] vma
drivers/gpu/drm/i915/display/intel_dpt.c:136:21: got void [noderef] __iomem *[assigned] iomem

v2: The code moved into intel_dpt.c

drm/i915/dp: add max data rate calculation for UHBR rates

DP 2.0 UHBR link rates always use 128b/132b channel encoding, which has
a different data bandwidth efficiency from 8b/10b. The computation is
slightly convoluted due to the units we use; this is all explained in
the added comment.

v2: Clarified comment (Manasi)
