A new application level feature has NAT running out of SRAM, DDR, or
both. The addtion of just this feature's header to the kernel will
allow it to be propagated to older kernels, such that they can be
compatible (in terms of structure size) with the new application level
feature.

GPIOs that can be configured as wakeup are routed to the PDC wakeup
interrupt controller and from there to the GIC interrupt controller. On
some QCOM SoCs, the interface to the GIC for wakeup capable GPIOs have
additional hardware registers that need to be configured as well to
match the trigger type of the GPIO. This register interfaces the PDC to
the GIC and therefore updated from the PDC driver.
Typically, the firmware intializes the interface registers for the
wakeup capable GPIOs with commonly used GPIO trigger type, but it is
possible that a platform may want to use the GPIO differently. So, in
addition to configuring the PDC, configure the interface registers as
well.

Add irqchip calls to set/get interrupt state from the parent interrupt
controller. When GPIOs are renabled as interrupt lines, it is desirable
to clear the interrupt state at the GIC. This avoids any unwanted
interrupt as a result of stale pending state recorded when the line was
used as a GPIO.

Add some nascent infrastructure for handling implementation-specific
details outside the flow of the architectural code. This will allow us
to keep mutually-incompatible vendor-specific hooks in their own files
where the respective interested parties can maintain them with minimal
chance of conflicts. As somewhat of a template, we'll start with a
general place to collect the relatively trivial existing quirks.

Clean up the remaining accesses to GR0 registers, so that everything is

first step towards moving it out of the way entirely. Although GR0 does
technically contain some 64-bit registers (sGFAR and the weird SMMUv2
HYPC and MONC stuff), they're not ones we have any need to access.

To keep register-access quirks manageable, we want to structure things
to avoid needing too many individual overrides. It seems fairly clean to
have a single interface which handles both global and context registers
in terms of the architectural pages, so the first preparatory step is to
rework cb_base into a page number rather than an absolute address.

The arm_smmu_power_off_atomic() function derives the pointer to
the SMMU device by incorrectly assuming that all devices in the
power resources structures store that pointer as part of their
driver data.
While this is true for devices that represent an SMMU, this is
not the case for the devices that represent the TBUs, as they
store the TBU structures instead of a pointer to the SMMU device.
Thus, require the SMMU device as a parameter to the
arm_smmu_power_off[_atomic] functions so that it can be used
correctly.
