[PATCH v2 06/10] drm: omapdrm: Rename GEM DMA sync functions

[Laurent Pinchart]

The omap_gem_cpu_sync() function operates at a page level, while the
omap_gem_dma_sync() function operates at a buffer level. Rename them to
omap_gem_cpu_sync_page() and omap_gem_dma_sync_buffer() respectively to
avoid confusion.
