[PATCH v2 0/8] hw/riscv/virt.c: aplic/imsic DT fixes

[Daniel Henrique Barboza]

Hi,

This is a series that is being spun from the reviews given on patch 1
[1]. We'll fix some DT validation issues we have in the 'virt' machine
[2] that aren't related to missing extensions in the DT spec.

I'll leave to maintainers to squash the patches as they see fit. I
split it this way to make it easier to bissect possible bugs that these
individual changes can cause.

These are the types of DT warnings solved by this series:

[3] explains how to run 'dt-validate' to reproduce them. To generate a
'processed schema' file what I did was:

- in the Linux kernel tree, run 'make dt_binding_check'. Please note
  that this might require installation of additional python stuff
  (e.g.swig, python3-devel)

- I used the generated file 
'Documentation/devicetree/bindings/processed-schema.json'
  as a 'processed schema'.

Series applicable on both master and alistair/riscv-to-apply.next. 

Changes from v1:
- added patches 2 to 7 to fix the dt-validate warnings on imsics and
  aplic notes
