Subject: hwaccess: replace macros by C code

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