winsys/svga: Add support for new surface ioctl, multisample pattern
Kernel driver version 2.15 added new surface ioctl named:
DRM_VMW_GB_SURFACE_CREATE_EXT
DRM_VMW_GB_SURFACE_REF_EXT
The new ioctl has support for 64-bit svga3d_flags if
DRM_VMW_PARAM_SM4_1 is available.
Multisampling surface mob size calculation is added. Also synced the
relevant header update.
svga device modified the surface define command V3 with new parameter
multisampling pattern. Adding support for that in winsys.
