[PATCH v3 0/4] QEMU: Fix RISC-V virt & spike machines' dtbs

[Conor Dooley <mail@conchuod.ie>]

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.

I mostly opted for what appeared to be the smallest change that would
fix the warnings, partly due to my inexperience with the QEMU codebase.
A "sister" patchset for the kernel will clear the remaining warnings.
Thanks to Rob Herring for reporting these issues [1],
Conor.

Changes since v2:
- move the syscon subnodes back to the top level instead of into the
  syscon node
Changes since v1:
- drop patch 1

To reproduce the errors:
./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb
dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb
(The processed schema needs to be generated first)
