[PATCH v5 4/4] arm64: dts: qcom: sc8280xp-x13s: enable camera privacy indicator

[Aleksandrs Vinarskis <alex@vinarskis.com>]

Leverage newly introduced 'leds' and 'led-names' properties to pass
indicator's phandle and function to v4l2 subnode. The latter supports
privacy led since couple of years ago under 'privacy-led' designation.
Unlike initially proposed trigger-source based approach, this solution
cannot be easily bypassed from userspace, thus reducing privacy
concerns.
