V4L/DVB: vpfe-capture: converting ccdc drivers to platform-drivers
This adds platform code for ccdc driver on DM355 and DM6446.
1) new ccdc platform devices added
2) added clock aliases master and slave for CCDC clocks
3) added dm355_ccdc_setup_pinmux() pin-mux setup hook in dm355 ccdc driver platform data
