drm/vmwgfx: switch from ioremap_cache to memremap
drm/vmwgfx: switch from ioremap_cache to memremap

Per commit 2e586a7e017a "drm/vmwgfx: Map the fifo as cached" the driver
expects the fifo registers to be cacheable.  In preparation for
deprecating ioremap_cache() convert its usage in vmwgfx to memremap().
