With calling dev_pm_set_wake_irq() to set MXC_V2 RTC as wakeup source
for suspend, generic wake irq mechanism will automatically enable
it as wakeup source when suspend, then the suspend/resume callback
which are ONLY for enabling/disabling irq wake can be removed, it
simplifies the code.

The commit 1921cab1 ("rtc: rx8025: Switch to use %ptR") converted
the driver to use new %p extension, but actually used wrong type of
the parameter in one case.

Fix a parameter to %ptR in rx8025_read_alarm().
