When entering suspend while an wakeup alarm is set, enable_set_wake
should make sure that the RTC interrupt keep being enabled and the
.irq_set_wake for the RTC interrupt get called. However, since the
driver uses the suspend_noirq callback, the call to enable_irq_wake
has been made after disabling the interrupts. While .irq_set_wake
has been called properly, the interrupt remained disabled.

Use the suspend callback to call enable_irq_wake early enough to
ensure the RTC interrupt remains enabled.

Using gpio_request_array()/gpio_free_array() can make the code
simpler because it can set the direction and initial value
in one shot and the for loop is unnecessary.

Also, struct v3020_gpio is removed, because the struct v3020_gpio
is replaced with struct gpio.

On some !ARM 32bits platforms, the following compilation error happens
because of the division on a 64bits value in mtk_rtc_read_time():

According to C99, %2.s means 'print two spaces' (a precision of
. without following digits or * means 0). The kernel's printf
implementation, however, treats that case as if no precision was
given, but relying on that quirk is rather silly. Also, since no -
(aka left-justify) flag is given, the field with of 2 would then cause
the alarm->enabled case to come out as "o n". Deobfuscate it.

The GIC chained handlers use do_IRQ() to call the subhandlers.  This
means that irq_enter() calls get nested, which leads to preempt count
looking like we're in nested interrupts, which in turn leads to all
system time being accounted as IRQ time in account_system_time().

Fix it by using generic_handle_irq().  Since these same functions are
used in some systems (if cpu_has_veic) from a low-level vectored
interrupt handler which does not go throught do_IRQ(), we need to do it
conditionally.

Currently, we can ask to authenticate DATA chunks and we can send DATA
chunks on the same packet as COOKIE_ECHO, but if you try to combine
both, the DATA chunk will be sent unauthenticated and peer won't accept
it, leading to a communication failure.

This happens because even though the data was queued after it was
requested to authenticate DATA chunks, it was also queued before we
could know that remote peer can handle authenticating, so
sctp_auth_send_cid() returns false.

The fix is whenever we set up an active key, re-check send queue for
chunks that now should be authenticated. As a result, such packet will
now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.
