drm/i915: Don't pass pitch to intel_compute_page_offset()
intel_compute_page_offset() can dig up the correct pitch from the fb
itself, no need for the caller to pass it in.
A bit of extra care is needed for the lower level
_intel_compute_page_offset() since that one gets called before the
rotated pitch under intel_fb is populated. Note that we don't actually
call it with anything but DRM_ROTATE_0 there so we wouldn't actually
look up the rotated pitch there, but still, leave the pitch as something
the caller has to pass to _intel_compute_page_offset() as an
indicator that something is a bit special.
This leaves 'stride_div' in the skl plane update hooks as a mostly useless
variable so just get rid of it.
v2: Add a note why stride_div got nuked
v3: Extract intel_fb_pitch() since it can be useful later
