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.

mfd: rsmu: Split core code into separate module Linking a file into two modules can have unintended side-effects and produces a W=1 warning: scripts/Makefile.build:236: drivers/mfd/Makefile: rsmu_core.o is added to multiple modules: rsmu-i2c rsmu-spi Make this one a separate module instead.
