[PATCH v2 1/8] arm64: dts: qcom: x1e80100-crd: mark l12b and l15b always-on

[Johan Hovold]

The l12b and l15b supplies are used by components that are not (fully)
described (and some never will be) and must never be disabled.

Mark the regulators as always-on to prevent them from being disabled,
for example, when consumers probe defer or suspend.
