MIPS: Alchemy: Remove bogus static/inline specifiers

The recent io_remap_pfn_range() rework applied the static and inline
specifiers to the implementation of io_remap_pfn_range_pfn() on MIPS
Alchemy, mirroring the same change on other platforms. However, this
function is defined in a source file and that definition causes a
conflict with its declaration. Fix this by dropping the specifiers.
