Min Li 013a3e7c79 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.

Min Li a1867f85e0 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.
