Check that the apid for an SPMI interrupt falls between the
min_apid and max_apid that can be handled by the APPS processor
before invoking the per-apid interrupt handler:
periph_interrupt().
This avoids an access violation in rare cases where the status
bit is set for an interrupt that is not owned by the APPS
processor.

Currently, cleanup_irq() is invoked when a peripheral's interrupt
fires and there is no mapping present in the interrupt domain of
spmi interrupt controller.
The cleanup_irq clears the arbiter bit, clears the pmic interrupt
and disables it at the pmic in that order. The last disable in
cleanup_irq races with request_irq() in that it stomps over the
enable issued by request_irq. Fix this by not writing to the pmic
in cleanup_irq. The latched bit will be left set in the pmic,
which will not send us more interrupts even if the enable bit
stays enabled.
When a client wants to request an interrupt, use the activate
callback on the irq_domain to clear latched bit. This ensures
that the latched, if set due to the above changes in cleanup_irq
or when the bootloader leaves it set, gets cleaned up, paving way
for upcoming interrupts to trigger.
With this, there is a possibility of unwanted triggering of
interrupt right after the latched bit is cleared - the interrupt
may be left enabled too. To avoid that, clear the enable first
followed by clearing the latched bit in the activate callback.

The cleanup_irq() was meant to clear and mask interrupts that were
left enabled in the hardware but there was no interrupt handler
registered for it. Add an error print when it gets invoked.

The spmi arbiter device spawns spmi_devices which in turn spawn
platform_devices for pmic peripherals.
Move the arbiter's driver init to arch_initcall so that the subsequent
devices it spawns get instantiated earlier.

Change the initcall level for the SMMU driver to subsys_initcall
so that the IOMMU devices get probed earlier in the bootup
sequence. This helps reduce the number of probe retrials for
client drivers that depend on an IOMMU.

A spmi controller may have many child devices, which together may take
a signifigant amount of time to register and probe. Reduce this effect
by probing asynchronously.

Add support for a streaming interface for TMC ETR to allow for continuous
log collection to secondary storage. An interrupt based mechanism is used
to stream out the data from the device. The streaming interface cannot be
used in conjunction with the traditional ETR read operation.
