video: mb862xx: improve board-specific Lime configuration
To avoid board-specific code accessing the mb862xx registers directly, the public function mb862xx_probe() has been introduced. Furthermore, the "Change of Clock Frequency" and "Set Memory I/F Mode" registers are now defined by CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx__MMR, respectively. The BSPs for the socrates and lwmon5 boards have been adapted accordingly. Signed-off-by: Wolfgang Grandegger <wg@denx.de>
