rtc: remove and clarify unneeded externs
When CONFIG_HPET_EMULATE_RTC is defined the external declaration of hpet_rtc_interrupt is redundant due to the inclusion of hpet.h. When !CONFIG_HPET_EMULATE_RTC we make it clear that hpet_rtc_interrupt is not used by defining it to return zero. Signed-off-by: Carlos R.
