[PATCH v2 15/17] drm/vmwgfx: Add surface define v4 command

["Roland Scheidegger (VMware)" <rscheidegger.oss@gmail.com>]

From: Deepak Rawat <drawat.floss@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.
