build: define RTC_SUPPORT as a bool
Currently, RTC_SUPPORT is defined as a tristate, with 'depends on m', which is supposed to only let it be set to 'm' or 'n'. However, scripts/target-metadata.pl will 'select' it, or setting it to 'y', which defeats it's 'depends on m' restriction. The users of the symbol are not expecting it to be necessarily 'm' either, so we can safely use it as bool. Newer versions of Linux 'conf' will issue a warning when it detects such unmet dependencies, and will set it to 'n' instead of 'y', as the current version does. In all cases, 'm' is never used.
