    mfd: rsmu: Split core code into separate module
    
    [ Upstream commit c879a8c39dd55e7fabdd8d13341f7bc5200db377 ]
    
    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.
