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 Signed-off-by: Jens Scharsig <esw@bus-elektronik.de> [agust@denx.de: fixed some style issues before applying] Signed-off-by: Anatolij Gustschin <agust@denx.de>
