drm/i915: Introduce intel_dumb_fb_max_stride()

Browse source

Wrap intel_plane_fb_max_stride() in intel_dumb_fb_max_stride()
for the purposes of dumb fb creation. I want to change
intel_plane_fb_max_stride() to take a 'struct drm_format_info'
instead of the 'u32 pixel_format' so we need an excplicit format
info lookup in the dumb fb path and I don't really want to have
that in i915_gem_dumb_create() directly.

This makes intel_plane_fb_max_stride() internal to the display
code again, and thus we can pass in struct intel_display instead
of struct drm_device.
