drivers: pinctrl_nrf: Fix nrf_pin_configure() implementation

This is a follow-up to commit fd0767557439d04c4a220a9857e901d8d71498db.

The above commit was supposed to introduce overriding of the S0S1
drive setting with S0D1 for TWI/TWIM peripherals, but since it did
not properly update the `nrf_pin_configure()` function (the `drive`
parameter was only added in the function signature, but then it was
not used...), the drive setting was in fact not overridden.
This commit corrects this embarrassing oversight.
