[COMMON] g2d: add cache maintenance

If G2D is a shareable device, CPU caches do not need to be manually
maintained by G2D driver. But there is one exception when shareable
G2D needs to read a cacheable buffer written by a non-shareabe device.
G2D driver should invalidate speculatively prefetched data possibly
loaded into CPU caches before reading the buffer shareably.
