Subject: [PATCH RFC v2 5/7] pinctrl: Delete PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS
 support

The argument for PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS is supposed to
be expressed in terms of ohms.  But the pinctrl-scmi driver was
implementing it the same as PIN_CONFIG_OUTPUT and writing either a
zero or one to the pin.

The SCMI protocol doesn't have an support configuration type so just
delete this code instead of fixing it.
