Zhenyu Wang a9d48b3eae drm/i915: Fix FDI M/N setting according with correct color depth ...

commit 58a27471d00dc09945cbcfbbc5cbcdcd3c28211d upstream.

FDI M/N calculation hasn't taken the current pipe color depth into account,
but always set as 24bpp. This one checks current pipe color depth setting,
and change FDI M/N calculation a little to use bits_per_pixel first, then
convert to bytes_per_pixel later.

This fixes display corrupt issue on Arrandle LVDS with 1600x900 panel
in 18bpp dual-channel mode.
