arm64: dts: qcom: x1e001de-devkit: mark l12b and l15b always-on

commit 7d328cc134f7db1e062f616a30cffe96fbc43abb upstream.

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.
