Add ACPI support in the fsl-mc driver. Driver parses MC DSDT table to
extract memory and other resources.
Interrupt (GIC ITS) information is extracted from the MADT table
by drivers/irqchip/irq-gic-v3-its-fsl-mc-msi.c.
IORT table is parsed to configure DMA.

The DPRC driver is not taking into account the msi-map property
and assumes that the icid is the same as the stream ID. Although
this assumption is correct, generalize the code to include a
translation between icid and streamID.
Furthermore do not just copy the MSI domain from parent (for child
containers), but use the information provided by the msi-map property.
If the msi-map property is missing from the device tree retain the old
behaviour for backward compatibility ie the child DPRC objects
inherit the MSI domain from the parent.

At the moment, the core ITS driver imposes the allocation to be
in chunks of 32. As we want to relax this on a per bus basis, let's
move the the the allocation constraints to each bus.
No functionnal change.

We want the IIO/Staging fixes in here, and to resolve a merge problem
with the move of the fsl-mc code.

Now that the fsl-mc bus core infrastructure is out of staging, the
remaining irqchip glue code used (irq-gic-v3-its-fsl-mc-msi.c) goes
to drivers/irqchip.
Create new Kconfig option for irqchip code that depends on
FSL_MC_BUS and ARM_GIC_V3_ITS. This ensures irqchip code only
gets built on ARM64 platforms. We can now remove #ifdef
GENERIC_MSI_DOMAIN_OPS as it was only needed for x86.
