dt-bindings: arm: Allow 32-bit 'cpu-release-addr' values 



While the DT Spec says 'cpu-release-addr' is always 64-bit, some 32-bit Arm
DTs used a 32-bit value. We're now stuck with those cases, so add uint32 as
a valid type.

    description:

      The DT specification defines this as 64-bit always, but some 32-bit Arm

      systems have used a 32-bit value which must be supported.

      Required for systems that have an "enable-method"

        property value of "spin-table".

      On ARM v8 64-bit systems must be a two cell

        property identifying a 64-bit zero-initialised

        memory location.
