Removed the pinctrl and pin{mux,conf} for the control pins because:
1. The only need for them is for userspace control via flash_fp_mcu
2. cros-ec doesn't know what to do with them, and even if it did,
   it would interfere with flash_fp_mcu at the most inopportune times

Since we're not using hogs, we rely on AP firmware to set all the
control pins correctly.

We have essentially the same patch downstream, so I suppose the AP FW
indeed takes care of configuring the FP pins as needed :)
