rtc: make rtc_update_irq callable with irqs enabled
The rtc_update_irq() might be called with irqs enabled, if a interrupt
handler was registered without IRQF_DISABLED. Use
spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock.
Also update kerneldoc and drivers which do extra work to follow the
current interface spec, as suggestted by David Brownell.
