CTCaer 0da69efd07 bdk: pinmux: always detach I2C4 pins from I2C3 pm ...

Generally I2C3 communication can work via I2C3 or I2C4 pins.
Defaults are fine as long as one of the pin groups are floating or grounded or
both share I2C traces.

In NX boards I2C4 SDA is used for GC and connected to 1V8.
So if a GC is slotted, I2C3 works, if not, no communication is possible.

This config was done previously inside I2C3 consumer driver (touchscreen).
Now it's moved inside pinmux_config_i2c.
