ARM exclusively uses GENERIC_IRQ_MULTI_HANDLER, so at some point
set_handle_irq() needs to be called to handle system-wide
interrupts.

For all DT-enabled boards, this call happens down in the
drivers/irqchip subsystem, after locating the target irqchip
driver from the device tree.

We still have a few instances of the boardfiles with machine
descriptors passing a machine-specific .handle_irq() to the
ARM kernel core.

Get rid of this by letting the few remaining machines consistently
call set_handle_irq() from the end of the .init_irq() callback
instead and diet down one member from the machine descriptor.

Building with "W=1" warns about missing declarations for
two functions in the mmp irqchip driver:

drivers/irqchip/irq-mmp.c:248:13: error: no previous prototype for 'icu_init_irq'
drivers/irqchip/irq-mmp.c:271:13: error: no previous prototype for 'mmp2_init_icu'

The declarations are present in an unused header, but since there is no
caller, it's best to just remove the functions and the header completely,
making the driver DT-only to match the state of the platform.

With the last non-OF, non-ACPI user of the GIC being removed in
e73307b9ebc4 ("ARM: cns3xxx: remove entire platform"), we can finally
drop the entry point and do some minor cleanup.

We also make the driver depend on CONFIG_OF, which is required
even when CONFIG_ACPI is selected.

The functions icu_init_irq and mmp2_init_icu are exported
from this code, so declare them in the header file to avoid
the following sparse warnings:

drivers/irqchip/irq-mmp.c:248:13: warning: symbol 'icu_init_irq' was not declared. Should it be static?
drivers/irqchip/irq-mmp.c:271:13: warning: symbol 'mmp2_init_icu' was not declared. Should it be static?

Pull gpio updates from Bartosz Golaszewski:
 "We have lots of small changes all over the place, but no huge reworks
  or new drivers:

   - use ioread()/iowrite() interfaces instead of raw inb()/outb() in
     drivers

   - make irqchips immutable due to the new warning popping up when
     drivers try to modify the irqchip structures

   - add new compatibles to dt-bindings for realtek-otto, renesas-rcar
     and pca95xx

   - add support for new models to gpio-rcar, gpio-pca953x &
     gpio-realtek-otto

   - allow parsing of GPIO hogs represented as children nodes of
     gpio-uniphier

   - define a set of common GPIO consumer strings in dt-bindings

   - shrink code in gpio-ml-ioh by using more devres interfaces

   - pass arguments to devm_kcalloc() in correct order in gpio-sim

   - add new helpers for iterating over GPIO firmware nodes and
     descriptors to gpiolib core and use it in several drivers

   - drop unused syscon_regmap_lookup_by_compatible() function

   - correct format specifiers and signedness of variables in GPIO ACPI

   - drop unneeded error checks in gpio-ftgpio

   - stop using the deprecated of_gpio.h header in gpio-zevio

   - drop platform_data support in gpio-max732x

   - simplify Kconfig dependencies in gpio-vf610

   - use raw spinlocks where needed to make PREEMPT_RT happy

   - fix return values in board files using gpio-pcf857x

   - convert more drivers to using fwnode instead of of_node

   - minor fixes and improvements in gpiolib core"

quirks and code dealing with that boot path and rely solely on
device tree boot.

Fix some missing static keywords that the kernel test robot
was complaining about while we're at it.

Move the name output to the relevant callback, which allows us
some nice cleanups (mostly owing to the fact that the driver is
now DT only.

The new memreserve cpuhp callback only needs to survive up until a point
where every CPU in the system has booted once. Beyond that, it becomes a
no-op and can be put in the bin.
