rtc: add rtc_shutdown api to service pending work
During shutdown/reboot process, its better to
finish any pending irqwork so that the work is
not scheduled after devices like i2c are shutdown.
This patch provides hook to be called from rtc driver after disabling
rtc irq. Also any further request to access rtc_class_ops will
be prohibited.
