[PATCH] mfd: intel_soc_pmic_crc: Add support for non ACPI instantiated i2c_client

[Hans de Goede <hdegoede@redhat.com>]

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).
