arm64: dts: qcom: x1e80100-yoga-slim7x: mark l12b and l15b always-on

Browse Source 
commit f43a71dc6d8d8378af587675eec77c06e0298c79 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.
