pinctrl: renesas: Factor out common R-Mobile bias handling

Browse source

The pin control sub-drivers for SH/R-Mobile SoCs contain almost
identical bias handling.  The only SoC-specific part is the mapping from
pin numbers to PORTnCR registers.

Reduce code duplication by factoring out the bias handling to the common
pinctrl.c code.  Use a callback to handle the pin/register mapping.
