Add IRQC interrupt controller support to r8a7790 by

the GIC. On r8a7790 the external IRQ pins routing is
handled by the PFC which is excluded from this patch.
Both platform devices and DT devices are added in this

During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.
It was ok at the time of the support of only the A10 and A13 that
look pretty much the same; but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...
Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

05ec260 mfd:db8500-prcmu: update resource passing
All DBx5x0 based SoCs have access to two Tightly Coupled Memory
(TCM) locations based on the PRCMU itself. One area from program
memory (TCPM) and one for data memory (TCDM). The PRCMU needs to
know where these are in order to function correctly. However,
these are currently passed though platform device resources, which
can only be obtained if Device Tree booting isn't in use. Thus we
must also support them in DT by supplying them through the PRCMU
node.
