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

Browse Source 
commit ff6ba96378367133b66587bd3ee9f068a39ff3a9 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.
