regmap/hexagon: Properly fix the generic IO helpers
I was too naive in just including <asm-generic/io.h> into
hexagon: one has to specify defines for every call that uses
a (static) inline or this will not work.
Fix it up by providing proper defines for all shorthands that
hexagon provides.
Compile-tested with hexagon LLVM which is the only working cross
compiler for hexagon ATM after commenting out the
-fno-inline-functions-called-once switch which isn't working
with LLVM.
