i2c: synquacer: fix enumeration of slave devices
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.
Fixes: 0d676a6c4390 ("i2c: add support for Socionext SynQuacer I2C controller")
