* Default function assigns controller for I2C port with modulo operation. If
* the I2C ports used are greater than MCHP_I2C_CTRL_MAX, then I2C ports will
* share the controller. Typically Type-C chips need individual controller per
* port because of heavy I2C transactions. Hence, define a board specific

* MCHP_I2C_CTRL_MAX.
