Subject: [PATCH v1 2/2] arm64: dts: qcom: x1e80100-dell-xps13-9345: fix nvme regulator boot glitch

The NVMe regulator has been left enabled by the boot firmware. Mark it
as such to avoid disabling the regulator temporarily during boot.

Based on https://lore.kernel.org/all/20241016145112.24785-1-johan+linaro@kernel.org/

Fixes: f5b788d0e8cd ("arm64: dts: qcom: Add support for X1-based Dell XPS 13 9345")
Signed-off-by: Aleksandrs Vinarskis <alex.vinarskis@...il.com>
