drm/i915: revert a few more watermark commits

This is a squash of the following commits:

Revert "drm/i915: Drop intel_update_sprite_watermarks"
This reverts commit c762c937c137096516b5507959ae267e787f0b7b.

Revert "drm/i915/ivb: Move WaCxSRDisabledForSpriteScaling w/a to atomic check"
This reverts commit 39498bb0ad9e1e3270f8013184bfb16ae7666aef.

Revert "drm/i915/skl: Eliminate usage of pipe_wm_parameters from SKL-style WM (v3)"
This reverts commit 32b0e358ea4b5e2d1bd0ccbb8bc85d5eb9ca1b5d.

With these reverts, SKL finally stops failing every single FBC test
with FIFO underrun error messages. After some brief testing, it also
seems that this commit prevents the machine from completely freezing
when we run igt/kms_fbc_crc (see fd.o #92355).
