ptp: idt82p33: use rsmu driver to access i2c/spi bus rsmu (Renesas Synchronization Management Unit ) driver is located in drivers/mfd and responsible for creating multiple devices including idt82p33 phc, which will then use the exposed regmap and mutex handle to access i2c/spi bus.

mfd: Add Renesas Synchronization Management Unit (SMU) support Add support for ClockMatrix(TM) and 82P33xxx families of timing and synchronization devices. The access interface can be either SPI or I2C. Currently, it will create 2 types of MFD devices, which are to be used by the corresponding rsmu character device driver and the PTP hardware clock driver, respectively.
