[PATCH 08/17] drm/vmwgfx: Support SM5 shader type in command buffer

[rscheidegger.oss at gmail.com]

From: Deepak Rawat <drawat.floss at gmail.com>

Virtual device now supports new shader types, allow them as valid shader
type in command buffer. Also add per shader bind info in binding manager
state for new shader type.
