Enable compile testing for Realtek pin controller drivers for increased
build and static checkers coverage.  PINCTRL_RTD uses
pinconf_generic_dt_node_to_map(), thus needs OF.

Add support for Realtek RTD1625 SoC using the realtek common pinctrl driver.

This patch introduces the RTK_PIN_CONFIG_V2 and RTK_PIN_CONFIG_I2C macros,
which are required to describe the specific register layout and electrical
features (such as slew rate and high VIL) of the RTD1625 pins.

Add support for configuring slew rate, input voltage level and high VIL
mode. This involves updating the pin configuration parsing logic to handle
PIN_CONFIG_SLEW_RATE, PIN_CONFIG_INPUT_VOLTAGE_UV and the new custom
property "realtek,high-vil-microvolt".

The argument originates from pinconf_to_config_argument(), which returns a
u32. Therefore, the arg parameter should be an unsigned int instead of enum
pin_config_param.

Replace NULL check with IS_ERR() for devm_platform_ioremap_resource()
return value. Use dev_err_probe() for error handling to maintain
consistency with the rest of the probe function.

Add system suspend and resume capabilities to the common Realtek pinctrl
library. This enables saving and restoring pin configurations during the
noirq phase for SoCs that define register ranges.
