Local functions should be marked static to prevent them from

This quiets the following sparse warnings:
warning: symbol 'ni_release_gpct_mite_channel' was not declared. Should it be static?
warning: symbol 'ni_prime_channelgain_list' was not declared. Should it be static?

This results in a compiler warning about the unused function
ni_release_gpct_mite_channel when compiling ni_atmio.c. It was unused
before of course, but now it is static, the compiler realizes it!
It could be fixed for now by moving the '#ifdef PCIDMA' and matching
'#endif' to surround the whole function, though I guess we want to try
and get rid of the #ifdef's eventually. It's tricky because
ni_mio_common.c isn't a standalone compilation unit, it's #include'd by
some other .c files. We might need to have a go at splitting it up at
some point.
