[PATCH i-g-t 04/12] lib/intel_bufops: Add Tile4 in linear_to and to_linear helpers

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

intel_buf_to_linear() and linear_to_intel_buf() allows easy tile/detile,
only thing they need is to select appropriate implementation. There's
missing switch for Tile4 so let's add it.
