The sh_rtc_set_irq_wake() function is only called from the suspend/resume handlers
that may be hidden, causing a harmless warning:
drivers/rtc/rtc-sh.c:724:13: error: 'sh_rtc_set_irq_wake' defined but not used [-Werror=unused-function]
static void sh_rtc_set_irq_wake(struct device *dev, int enabled)
The most reliable way to avoid the warning is to remove the existing #ifdef
and mark the two functions as __maybe_unused so the compiler can silently
drop all three when there is no reference.
Fixes: dab5aec64bf5 ("rtc: sh: add support for rza series")
