Petr Štetiar cbbef976e2 build: dtc: Disable noisy warnings by default
While helping with review and build testing of a few 4.19 pull requests,
I've noticed, that dtc compiler in OpenWrt uses different options then
upstream kernel, which is leading to a very noisy output[1]. It wouldn't
be that bad per se, but a lot of such warnings aren't easily fixable so
I think, that we should follow what upstream does and simply ignore^W
silence those noisy warnings.

So this patch tries to syncs dtc compiler flags with upstream kernel
till version 4.19.13, disabling those warnings as they were added in
upstream kernel:

 v4.6-rc1-2-gbc55398 dtc: turn off dtc unit address warnings by default

  The newly added dtc warning to check DT unit-address without reg
  property and vice-versa generates lots of warnings. Turn off the check
  unless building with W=1 or W=2.

 v4.11-rc2-11-g8654cb8 dtc: update warning settings for new bus and node/property

  dtc gained new warnings checking PCI and simple buses, unit address
  formatting, and stricter node and property name checking. Disable the
  new dtc warnings by default as there are 1000s. As before, warnings are
  enabled with W=1 or W=2. The strict node and property name checks are a
  bit subjective, so they are only enabled for W=2.

 v4.16-rc3-9-g4fd98e3 scripts: turn off some new dtc warnings by default

  The latest dtc update adds some new noisy warnings, so turn them off by
  default. Disable 'avoid_unnecessary_addr_size' and 'alias_paths'. They
  can be re-enabled by building with 'W=1'.

 v4.17-rc1-27-g74656b6 kbuild: disable new dtc graph and unit-address warnings

  dtc gained some new warnings for OF graphs and unique unit addresses,
  but they are currently much too noisy. So turn off
  'graph_child_address', 'graph_port', and 'unique_unit_address' warnings
  by default. They can be enabled by building dtbs with W=1.

Build tested on imx6 and ath79 with 4.14 and 4.19.
