[PATCH 15/17] drm/vmwgfx: Add surface define v4 command

From: Deepak Rawat <drawat.floss at gmail.com>
Surface define v4 added new member buffer_byte_stride. With this patch
add buffer_byte_stride in surface metadata and create surface using new
command if support is available.
Also with this patch replace device specific data types with kernel
types.
