drm/i915/wm: Use drm_get_format_info() in SKL+ cursor DDB allocation

Replace the technically inaccurate drm_format_info() with the
accurate drm_get_format_info() in the SKL+ cursor DDB
allocation code.

Since we're only interested in the linear modifier here, the two
functions do actually return the same information. But let's not
use drm_format_info() to avoid setting a bad example.
