drm/i915: Factor out intel_tile_width()
Pull the tile width calculations from intel_fb_stride_alignment() into a
new function intel_tile_width().
Also take the opportunity to pass aroun dev_priv instead of dev to
intel_fb_stride_alignment().
v2: Reorder argumnents to be more consistent with other functions
Change intel_fb_stride_alignment() to accept dev_priv instead of dev
v3: Deal with Y tilling (Daniel)
