This reverts commit 5b7e5676209120814dbb9fec8bc3769f0f7a7958.

Although including linux/irqchip/mxs.h is technically correct,
this clashes with the parallel removal of this include file
with 32bit ARM modernizing the low level irq handling as part of
5bb578a0c1b8 ("ARM: 9298/1: Drop custom mdesc->handle_irq()").

As such, this patch is not only unnecessary, it also breaks
compilation in -next. Revert it.

ARM: 9298/1: Drop custom mdesc->handle_irq()

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.

"Updates for the interrupt subsystem:

Core changes:

- Prevent a potential deadlock when initial priority is assigned to a
newly created interrupt thread. A recent change to plug a race
between cpuset and __sched_setscheduler() introduced a new lock
dependency which is now triggered. Break the lock dependency chain
by moving the priority assignment to the thread function.

- A couple of small updates to make the irq core RT safe.

- Confine the irq_cpu_online/offline() API to the only left unfixable
user Cavium Octeon so that it does not grow new usage.

- A small documentation update

Driver changes:

- A large cross architecture rework to move irq_enter/exit() into the
architecture code to make addressing the NOHZ_FULL/RCU issues
simpler.

- The obligatory new irq chip driver for Microchip EIC

- Modularize a few irq chip drivers

- Expand usage of devm_*() helpers throughout the driver code

Merge irqchip updates for Linux 5.16 from Marc Zyngier:

- A large cross-arch rework to move irq_enter()/irq_exit() into

Thanks to Mark Rutland for the huge effort!

- A few irqchip drivers are made modular (broadcom, meson), because

- A new driver for the Microchip External Interrupt Controller

- The irq_cpu_offline()/irq_cpu_online() API is now deprecated and
can only be selected on the Cavium Octeon platform. Once this
platform is removed, the API will be removed at the same time.

- A sprinkle of devm_* helper, as people seem to love that.

irq: remove handle_domain_{irq,nmi}()

Now that entry code handles IRQ entry (including setting the IRQ regs)
before calling irqchip code, irqchip code can safely call
generic_handle_domain_irq(), and there's no functional reason for it to
call handle_domain_irq().

Let's cement this split of responsibility and remove handle_domain_irq()
entirely, updating irqchip drivers to call generic_handle_domain_irq().

For consistency, handle_domain_nmi() is similarly removed and replaced
with a generic_handle_domain_nmi() function which also does not perform
any entry logic.

Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire
when they were called in an inappropriate context. So that we can
identify similar issues going forward, similar WARN_ON_ONCE() logic is
added to the generic_handle_*() functions, and comments are updated for
clarity and consistency.
