[PATCH v2] arm64: dts: qcom: sm6350-lena: Flatten gpio-keys pinctrl state

[Marijn Suijten]

Pinctrl states typically collate multiple related pins.  In the case of
gpio-keys there's no hardware-defined relation at all except all pins
representing a key; and especially on Sony's lena board there's only one
pin regardless. Flatten it similar to other boards [1].

As a drive-by fix, clean up the label string.
