powerpc: fsl_rio: Use of_range_to_resource() for "ranges" parsing
"ranges" is a standard property with common parsing functions. Users
shouldn't be implementing their own parsing of it. Refactor the FSL RapidIO
"ranges" parsing to use of_range_to_resource() instead.
One change is the original code would look for "#size-cells" and
"#address-cells" in the parent node if not found in the port child
nodes. That is non-standard behavior and not necessary AFAICT. In 2011
in commit 54986964c13c ("powerpc/85xx: Update SRIO device tree nodes")
there was an ABI break. The upstream .dts files have been correct since
at least that point.
