mfd: Rohm PMICs: Use platform_device_id to match MFD sub-devices
Thanks to Stephen Boyd I today learned we can use platform_device_id
to do device and module matching for MFD sub-devices!
Do device matching using the platform_device_id instead of using
explicit module_aliases to load modules and custom parent-data field
to do module loading and sub-device matching.
