d20747b7df ARM: dts: r8a7743: Add reset control properties
Add properties to describe the reset topology for on-SoC devices:
  - Add the "#reset-cells" property to the CPG/MSSR device node,
  - Add resets and reset-names properties to the various device nodes.

This allows to reset SoC devices using the Reset Controller API.

Note that all resets added match the corresponding module clocks.

37f0c804e5 ARM: dts: r8a7743: Remove unit-address and reg from integrated cache
The Cortex-A15 cache controller is an integrated controller, and thus
the device node representing it should not have a unit-addresses or reg
property.

387720c938 ARM: DTS: Fix register map for virt-capable GIC
Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

7add1da17a ARM: dts: r8a7743: Link ARM GIC to clock and clock domain
Link the ARM GIC to the INTC-SYS module clock, and add it to the SYSC
"always-on" PM Domain, so it can be power managed using that clock.

Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.
