rtc: omap: Use define directive for PIN_CONFIG_ACTIVE_HIGH
Clang warns when one enumerated type is implicitly converted to another:
drivers/rtc/rtc-omap.c:574:21: warning: implicit conversion from
enumeration type 'enum rtc_pin_config_param' to different enumeration

It is expected that pinctrl drivers can extend pin_config_param because
of the gap between PIN_CONFIG_END and PIN_CONFIG_MAX so this conversion
isn't an issue. Most drivers that take advantage of this define the
PIN_CONFIG variables as constants, rather than enumerated values. Do the
same thing here so that Clang no longer warns.
