blackfin: make name_to_gpio be a weak symbol
This required moving it into a C file from the header.
The only user of a non-default name_to_gpio is blackfin, therefore build tested
with the blackfin bct-brettl2 build, which is one I picked at random. Also
tested with a build for the ARM tec board which uses the default/fallback
implementation. Inspection with objdump shows that both have done the right
thing.
This change was requested by Marek during review of the sunxi patch series.
