The gpio_chip operations receive a pointer the gpio_chip struct which is
contained in the driver's private struct, yet the container_of call in those
functions point to the mfd struct defined in include/linux/mfd/tps65912.h.

The change:
7b8792bbdffdff3abda704f89c6a45ea97afdc62
gpiolib: of: Correct error handling in of_get_named_gpiod_flags
assumed that only one gpio-chip is registred per of-node.
Some drivers register more than one chip per of-node, so
adjust the matching function of_gpiochip_find_and_xlate to
not stop looking for chips if a node-match is found and
the translation fails.

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC.

In preparation to enable ARCH_MMP on ARM64, the include of mach/irqs.h
must be eliminated. mach/irqs.h was being included for IRQ_GPIO{0,1},
but these IRQs are always passed in as resources now. We can use irq0
and irq1 and get rid of IRQ_GPIOx. Get rid of the ifdef in the process
as it is no longer needed.

because sa1100 does not have a device for gpios, which is a requirement
for GPIOLIB_IRQCHIP. This will be the next step.

Low GPIO pins use an interrupt in SC interrupts space. However it's
possible to handle them as if all the GPIO interrupts are instead tied
to single GPIO handler, which later decodes GEDR register and
chain-calls next IRQ handler. So split first 11 interrupts into system
part (IRQ_GPIO0_SC - IRQ_GPIO10_SC) which work exactly like the rest of
system controller interrupts and real GPIO interrupts
(IRQ_GPIO0..IRQ_GPIO10). A single handler sa1100_gpio_handler then
decodes and calls next handler.

Similar to omap_gpio_irq_type() let's make sure that the GPIO
is usable as an interrupt if the platform init code did not
call gpio_request(). Otherwise we can get invalid device access
after setup_irq():

We can fix this the same way omap_gpio_irq_type() is handling it.
Note that the long term solution is to change the gpio-omap driver
to handle the banks as separate driver instances. This will allow
us to rely on just runtime PM for tracking the bank specific state.
