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 v4:
- Removed accidental , instead of ; in the last line
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
