ptp: clockmatrix: use rsmu driver to access i2c/spi bus

Browse Source 
rsmu (Renesas Synchronization Management Unit ) driver is located in
drivers/mfd and responsible for creating multiple devices including
clockmatrix phc, which will then use the exposed regmap and mutex
handle to access i2c/spi bus.
