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.
