[v4,0/2] fsi: Add IBM I2C Responder virtual FSI master

Message

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
