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

Browse Source 
[ Upstream commit abf89bc4bb09c16a53d693b09ea85225cf57ff39 ]

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.
