[PATCH v4 00/18] Cleanup for populate default bus

[Kefeng Wang]

This cleanup patchset cantains two parts.

Firstly, introduce a new way to populate the default bus, then, we can
drop unnecessary calls from the arch code, and do the same thing for
of_iommu_init() in [1].

Secondly, use helper of_platform_default_populate() in linux/of_platform
when possible, instead of calling of_platform_populate() with default
match table, After that, it is possible for driver code build as a module,
and no need to export of_default_bus_match_table anymore.

This patchset is based on Linux 4.6-rc5, and only test in arm/arm64 qemu
with defconfig.

Changes since v3:
- Get rid of by making of_platform_populate callable multiple times,
  sugguested by Rob Herring

Changes since v2:
- Add more acks
- Update based on v4.6-rc2, of-generic.c in sh and board-artpec6.c in arm
  are considered

Changes since v1:
- Add ack, test and review
- Remove v1 patch 14/15, the similar patch has posted and applied,
  see https://patchwork.kernel.org/patch/8096991/

v1:
