Subject: [PATCH 0/3] of: base: of_parse_phandle() fixes and new variant

This series is a result of the discussion in [1]. Rob suggested to convert
the index parameter to unsigned int and drop the check for negative values
and make them static inline.

It will also introduce a new variant of the function, although it is unused
for now. They will be needed when nvmem phandles are modified to take
additional arguments and need to retain backwards compatibility with older
device trees.
