Upon close examination, the issue seems easy to fix. Going to submit a
new set shortly.

sparc64 and hexagon don't have ioremap_uc defined. Hexagon also doesn't
have ioremap_wc but didn't report an issue before so devm_ioremap won't
have an problem.

Interestingly tho, majority of the archs include <asm-generic/io.h>,
thus having prototypes. These two archs and a few others don't. I'm
wondering if including the prototypes is actually the recommended
practice.
