  The I2C Responder (I2CR) is an I2C device that translates I2C commands
to CFAM or SCOM operations, effectively implementing an FSI master and
bus.

Changes since v3:
 - Rework the endian-ness in i2cr_write
 - Rework the tracing to include the i2c bus and device address

Changes since v2:
 - Fix the bindings again, sorry for the spam

Changes since v1:
 - Fix the binding document
 - Change the binding name
 - Clean up the size argument checking
 - Reduce __force by using packed struct for the command
