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

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")
