pinctrl: realtek: add rtd1625 pinctrl driver
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.

pinctrl: realtek: Fix return value and silence log for unsupported configs
Treating unsupported configurations as errors causes upper layers (like the
GPIO subsystem) to interpret optional features as hard failures, aborting
operations or printing unnecessary error logs.
For example, during gpiod_get(), the GPIO framework attempts to set
PIN_CONFIG_PERSIST_STATE. Since this driver does not support it, false
error reports are generated in dmesg.
Fix this by returning -ENOTSUPP and demoting the log level to dev_dbg.
