pinctrl: realtek: Initialise omitted offset fields to NA in config macros

The Realtek pinctrl driver uses NA (0xffffffff) as the sentinel for
unsupported pin configuration features.  However, RTK_PIN_CONFIG omits
input_volt_offset, slew_rate_offset, and hvil_offset, and
RTK_PIN_CONFIG_V2 omits slew_rate_offset and hvil_offset.  Because C99
designated initialisers zero-initialise omitted members, those fields
default to 0 instead of NA, causing rtd_pconf_parse_conf() to treat
unsupported features as valid at bit offset base_bit + 0 and corrupt
adjacent register bits.

Explicitly initialise the omitted offset fields to NA in RTK_PIN_CONFIG
and RTK_PIN_CONFIG_V2.
