sb1250-duart: __maybe_unused, etc. fixes
This is a set of small fixes addressing points raised with the original
driver submission. In particular, __maybe_unused is used rather than a
local hack and sbd_ops is made const. Additionally I have made two local
string variables automatic as rodata space was wasted for pointers
unnecessarily.
