There's no need to duplicate the interrupt-parent property in all DT
nodes as the kernel automatically walks parent nodes to find the
property. Specify it once in the root node only.

Add a DT node for the only system DMAC instance on r8a73a4. The RT DMAC
can be added later under the same multiplexer, because they can serve the
same slaves and use the same MID-RID values. Configuration data is
supplied to the driver, using a compatibility match string.

Currently DT compatibility strings of both types can be found in the kernel
sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be
followed and the former one is preferred. This patch converts the SDHI
MMC driver and its users to the common standard. This is safe for now, since
ATM no real products are using this driver with DT.

Add IRQC interrupt controller support to r8a73a4 by
hooking up two IRQC instances to handle 58 external
IRQ signals. There IRQC controllers are tied to SPIs
of the GIC. On r8a73a4 exact IRQ pin routing is handled
by the PFC which is excluded from this patch.

Both platform devices and DT devices are added in this
patch. The platform device versions are used to provide
a static interrupt map configuration for board code
written in C.

 - Architecture timer

No static virtual mappings are used, all the components
make use of ioremap(). DT_MACHINE_START is still wrapped
in CONFIG_USE_OF to match other mach-shmobile code.
