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