Some qcom platforms make some GPIOs or pins unavailable for use
by non-secure operating systems, and thus reading or writing the
registers for those pins will cause access control issues.
Introduce a DT property to describe the set of GPIOs that are
available for use so that higher level OSes are able to know what
pins to avoid reading/writing.

This looks fine except Andy's note to rename this ranges
to gpio-reserved-ranges for namespacing.
Ok! I'll rename to gpio-reserved-ranges.
Are you reposting this series as v3 with this fixed or does someone
else need to pick it up?
Yes I can do it today or tomorrow.
