hwaccess: replace macros by C code

Split the code for endian conversion into seperate files for big and
little endian. The buildsystem selects the correct file for the used
endiannes. Replace the swab macros with `static inline` c functions.
Define macros for returning the same or swaped value. Call those macros
in the endian specific files.
