On the U8500 platform there are four GPIO blocks, each with a 4K address
space, including the peripheral identification.  However, each of these
blocks have a varying number of banks, each of which have 32 GPIOs and
an interrupt line.

The current nomadik-gpio driver implementation can handle each of these
sub-banks easily with one instance each, but cannot as-is be hooked up
to them because it is an AMBA driver and it expects to see a peripheral
with the appropriate peripheral ids but having only one bank and only
one interrupt.

Solve this by converting the driver to a platform driver.

Since we register as a chained handler, we need to take care of acking
the parent irq.  Current code had the acking disabled because just
acking the interrupt disables it on some interrupt controllers (like the
VIC used on Nomadik).  However, not acking at all is incorrect because
interrupt controllers like the GIC need an EOI indication, which is done
in the ack routine.

Solve this by maskacking and unmasking it appropriately, similar to how
handle_level_irq operates.

If IRQ balancing is used on a multicore ARM system, PMU interrupt
lines may be relocated onto CPUs other than the one causing the
counter overflow. This can result in misattribution of events to
the wrong core and, in the case that the CPU handling the interrupt
has not experience counter overflow, the interrupt can be disabled
because the handler returns IRQ_NONE.

This patch adds the IRQF_NOBALANCING flag to the request_irq call
in perf_events.c.
