commit 95e0cf3caeb11e1b0398c747b5cfa12828263824 upstream.
The I2C host driver for SynQuacer fails to populate the of_node and
ACPI companion fields of the struct i2c_adapter it instantiates,
resulting in enumeration of the subordinate I2C bus to fail.

This is a cleaned up version of the I2C controller driver for
the Fujitsu F_I2C IP, which was never supported upstream, and
has now been incorporated into the Socionext SynQuacer SoC.
