mfd: intel_soc_pmic_crc: Add support for non ACPI instantiated i2c_client 



On some x86 Bay Trail tablets which shipped with Android as factory OS,
the DSDT is so broken that the PMIC needs to be manually instantiated by
the special x86-android-tablets.ko "fixup" driver for cases like this.

Add an i2c_device_id table so that the driver can match on manually
instantiated i2c_client-s (which lack an ACPI fwnode to match on).
