nfp: update nfp_X logging definitions

Previously it was not possible to determine which code path was responsible
for generating a certain message after a call to the nfp_X messaging
definitions for cases of duplicate strings. We therefore modify nfp_err,
nfp_warn, nfp_info, nfp_dbg and nfp_printk to print the corresponding file
and line number where the nfp_X definition is used.
