[PATCH v3] arm64: dts: qcom: sm8250-samsung-common: correct reserved pins

[PATCH v3] arm64: dts: qcom: sm8250-samsung-common: correct reserved pins

[Eric Gonçalves]

The S20 series has additional reserved pins for the fingerprint sensor,
GPIO 20-23. Correct it by adding them into gpio-reserved-ranges.

Fixes: 6657fe9e9f23 ("arm64: dts: qcom: add initial support for Samsung Galaxy S20 FE")

Changes in v3:
- Actually fixed <40 4> indentation
Sorry, I still had my editor on 4 spaces a tab

Changes in v2:
- "Fixed" the formatting of the <40 4> line
- Added Fixes tag

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: failed to guess base

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
