[PATCH 2/4] dt-bindings: mfd: syscon: allow two reg regions for gs101-pmu

[Peter Griffin]

To avoid dtschema warnings allow google,gs101-pmu to have
two reg regions.

I don't really like this patch, but also didn't want to submit the series
with a dtschema warning ;-)

Possibly a better solution is when Robs patch
`mfd: syscon: Allow syscon nodes without a "syscon" compatible` [1]

gets updated with a v2, we could remove syscon compatible from
gs101.dtsi (an ABI issue). If I understood his patch correctly,
it would mean this yaml update would then no longer be required.

Let me know your thoughts
