rtc: omap: Use define directive for PIN_CONFIG_ACTIVE_HIGH

commit c50156526a2f7176b50134e3e5fb108ba09791b2 upstream.

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
type 'enum pin_config_param' [-Wenum-conversion]
        {"ti,active-high", PIN_CONFIG_ACTIVE_HIGH, 0},
        ~                  ^~~~~~~~~~~~~~~~~~~~~~

                 ^

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.
