drm/i915/xe3p_lpd: Extend FBC support to UINT16 formats

Browse source

Starting Xe3p_LPD, FBC is supported on UINT16 formats as well. Also
UINT16 being a 64bpp format, will use cpp of 8 for cfb stride and thus
size calculations.

v2: simplify getting the cpp per format (Ville)
    simplify the pixel format is valid for xe3p_lp (Vinod)
