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].

[PATCH v2 06/11] arm64: defconfig: enable bpf/cgroup firewalling

[Marcel Ziswiler]

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

This avoids the following systemd warning:

[    2.618538] systemd[1]: system-getty.slice: unit configures an IP
 firewall, but the local system does not support BPF/cgroup firewalling.
[    2.630916] systemd[1]: (This warning is only shown for the first
 unit using IP firewalling.)

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Acked-by: Song Liu <songliubraving@fb.com>

Changes in v2:
- Add Song's acked-by tag.
