The real-time clock is a 5-byte binary counter. It is incremented 256 times
per second. The least significant byte is a count of fractional seconds.
The upper four bytes are a count of seconds. The realtime clock can
accumulate 136 years of seconds before rolling over.

Handling of extended interrupts (kickstart, wake-up, ram-clear) was
moved off to a work queue, but the interrupts aren't acknowledged
in the interrupt handler. This leads to a deadlock, if driver
is used with interrupts. To fix this we use a threaded interrupt, get rid
of the work queue and do locking with just the rtc mutex lock.

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.
