Revert "drm/i915: Display WA #1133 WaFbcSkipSegments:cnl, glk"

This reverts commit f0c41930d18ecc5bf1f7f4de7ca2fa76ccd07999.

HSD says "WA withdrawn. It was causing corruption with some images.
WA is not strictly necessary since this bug just causes loss of FBC
compression with some sizes and images, but doesn't break anything."
