ARM: S5PV210: Add support for M-5MOLS image sensor on UNIVERSAL_C210

Add voltage regulator definitions for M-5MOLS camera, platform data
definition for the sensor and MIPI-CSI receiver drivers.
Add CAM power domain dependencies for FIMC and CSIS devices.
Define required I2C0 bus timings. Setup camera port A GPIO.
