update the EB+MCF-EV123 board support
This patch updates the support for EB+MCF-EV123 board and needs
the [PATCH 1/2 V3] new video driver for bus vcxk framebuffers
* remove the board framebuffer driver
* use the common bus_vcxk framebuffer driver
* adds bmp support
* adds splashimage support
* fix serveral cosmetical errors
