Subject: [PATCH v1 1/1] arm64: dts: qcom: x1e80100-pmics: Disable pm8010 by default

pm8010 is a camera specific PMIC, and may not be present on some
devices. These may instead use a dedicated vreg for this purpose (Dell
XPS 9345, Dell Inspiron..) or use USB webcam instead of a MIPI one
alltogether (Lenovo Thinbook 16, Lenovo Yoga..).

Disable pm8010 by default, let platforms that actually have one onboard
enable it instead.

This fixes dmesg errors of PMIC failing to probe, and on Dell XPS 9345
fixes the issue of power button not working as power off/suspend (only
long press cuts the power).

Fixes: 2559e61e7ef4 ("arm64: dts: qcom: x1e80100-pmics: Add the missing PMICs")
