[PATCH 8/9] drm: dvbe: implement VBE/VESA blitting backend

Extend the dvbe core driver by a VESA/VBE backend that simply blits the data from a framebuffer into the hardware framebuffer on damage. Modesetting has to be done during the boot-process by the architecture code (same way as vesafb requires it). No runtime modesetting is allowed due to RealMode/Pr
