pinctrl: nuvoton: Add driver for WPCM450
This driver is based on the one for NPCM7xx, because the WPCM450 is a
predecessor of those SoCs. Notable differences:
- On WPCM450, the GPIO registers are not organized in multiple banks,
but rather placed continually into the same register block. This
affects how register offsets are computed.
- Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx
driver, this happens automatically when a GPIO is requested.
Some functionality implemented in the hardware was (for now) left unused
in the driver, specifically blinking and pull-up/down.
