The driver's Kconfig symbol is a boolean but nothing prevents the driver
to be built as a module instead of built-in. It is true that most system
integrators will choose the latter but the config should not restrict it.

The driver's init function is called at subsys init call level but the
dependencies provided by the driver are looked up by drivers that have
probe deferral support, so manual ordering of init calls isn't needed.

Currently the hi655x-pmic driver has names for interrupt mask
values, but not for the interrupt numbers themselves.

So to allow for interrupt numbers to have sane names, rename
the mask values with the _MASK postfix and use the existing
names as the interrupt name

While trying to get the powerkey to function, I found when
pressing the key, I would get infinitely repeating interrupts.

After digging around a bit, it seems we didn't set the ack_base
value for the regmap irqchip logic, so nothing was acking the
interrupt.

This patch adds the ack_base, which seems to make things work.

Previously the arizona_irq_thread implementation would call
handle_nested_irqs() to handle AOD interrupts without checking if any
were actually pending. The kernel will see these as spurious IRQs and
will eventually disable the IRQ.

This patch ensures we only launch the nested handler if there are AOD
interrupts pending in the codec.

The RPM in MSM8660/APQ8060 has different offsets to the selector
ACK and request context ACK registers. Make all these register
offsets part of the per-SoC data and assign the right values.

The bug was found by verifying backwards to the vendor tree in
the out-of-tree files <mach/rpm-[8660|8064|8960]>: all were using
offsets 3,11,15,23 and a select size of 4, except the MSM8660/APQ8060
which was using offsets 3,11,19,27 and a select size of 7.

All other platforms apart from msm8660 were affected by reading
excess registers, since 7 was hardcoded as the number of select
words, this patch makes also this part dynamic so we only write/read
as many select words as the platform actually use.

Symptoms of this bug when using msm8660: the first RPM transaction
would work, but the next would stall or raise an error since the
previous transaction was not properly ACKed as the ACK words were
read at the wrong offset.

The programming guidelines of the MAX77620 for servicing interrupt is:
1. When interrupt occurs from PMIC, mask the PMIC interrupt by
   setting GLBLM.
2. Read IRQTOP and service the interrupt.
3. Once all interrupts has been checked and serviced, the interrupt
   service routine un-masks the hardware interrupt line by clearing
   GLBLM.

Add the pre and post interrupt service handler for mask and unmask the
global interrupt mask bit (for step 1 and 3) as callback from regmap-irq.

The kernel expects the power_off function to not return, and if it does
it panics. Add a slight delay after the i2c write which turns off power
through the PMIC, to give capacitors etc. some time to drain.

Without this the kernel lives on long enough after the poweroff to
print the following on the serial console on my Mele A1000G quad:

[  248.583588] reboot: Power down
[  248.600490] Kernel pa
