The fan_sel_gpio DTS configuration of 3 didn't properly handle the fan pump controller for Ghana.

Add the fan_sel_gpio value of 255 for Ghana to indicate there is no fan select as BMC is the only controller for the pump fans.

Properly configure PWM0 for P0 pump fans and PWM3 for P1 pump fans.

Tested:
Verified in Ghana. Could change the pump fan speed for P1. Setting the PWM for P0 no longer causes P1 PWM to be set to 0.
