Reduce the stack usage by replacing the mOCT6100_RETRIEVE_NLP_CONF_DWORD
and mOCT6100_SAVE_NLP_CONF_DWORD macros with functions. Some compilers
do a better job of optimizing the local variables declared in those
macros than others.
For example, with gcc 4.3.0, running
]# make stackcheck | grep Oct6100 | head -n 20 | sed -e 's/^0\S* //g' | uniq
