drm/i915: s, fb->bits_per_pixel/8, pixel_size, in primary plane code
Use the pixel_size we got from drm_format_plane_cpp() instead of
fb->bits_per_pixel/8 when computing the primary plane page/linear
offsets. Avoids a few divs and makes the code more future proof
against funky pixel formats where bits_per_pixel isn't well defined.
This is what we already did in the sprite code.
Note that the relevant sprite patch was

drm/i915: Use pixel size for computing linear offsets into a sprite
This change was required on sprites because they support yuv formats
which have fb->bits_per_pixel undefined.
