[v2,00/11] arm64: prepare and add verdin imx8m mini support

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>


Fix strange hex notation and gpio-hog example, rebuild default
configuration, enable various relevant configuration options mainly to
be built as modules, add toradex,verdin-imx8mm et al. to dt-bindings and
finally, add initial support for Verdin iMX8M Mini.

Changes in v2:
- Added Laurent's reviewed-by tag.
- Added Rob's ack.
- New patch following full defconfig analysis as requested by Krzysztof.
- New patch following full defconfig analysis as requested by Krzysztof.
- Done full defconfig analysis as requested by Krzysztof.
- Add Song's acked-by tag.
- A similar change got accepted for imx_v6_v7_defconfig. Further
discussion may be found in [1].

- Explain why enabling it may be a good idea as requested by Krzysztof.
- Explain why enabling these may make sense and squash them relevant
  changes as requested by Krzysztof.
- Add Rob's acked-by tag.
- Fix Colibri vs. Verdin copy/paste mistake. Thanks to Francesco Dolcini
  <francesco.dolcini@toradex.com> for pointing that out to me.
- Remove bootargs which will be filled in by the bootloader as requested
  by Krzysztof.
- Remove the previously #ifdefed-out spi-nor as requested by Krzysztof.
- Fix capitalisation in cover-letter.
