Following patch series adds initial support for TWL6030 codec driver.

Changes from v2: - CODEC now handles scenarios where no platform data is passed - Removed GPIOLIB dependency of codec driver - Removed magic values, register reads instead - Added runtime constraints depending on sysclk - Added more constraints for switching to low-power mode - Use request_threaded_irq instead (oneshot support required) - wait_for_completion with timeout - Changelog now gives a better explanation of features and corresponding changes

Thanks, -Misa
