qcom,sc7280-mpss-pas compatible requires
just the xo clock and one reg space whereas
the qcom,sc7280-mss-pil compatible requires
the additional clks and reg spaces. We just
overload properties where re-use is possible
across boards. Hence it would be wrong to
list those clks/reg spaces as requirements
for the pas compatible.
