Previously, gfxfb_blt flushed the framebuffer on every call. Since a single drawing operation may invoke gfxfb_blt multiple times, this can result in unnecessary flushes. Instead, write updates to the shadow buffer (when present) and mark the affected area as dirty. Flushing is deferred so multiple gfxfb_blt calls can be coalesced into a single update. As before, only the dirty region is flushed. This fixes the slow bootloader problem in some platforms.
