The remaining uses of tg3_nvram_read_swab() either intended to read the
data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper
interpretations of the data.  For the former case, a direct replacement
of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order.  For
the latter case, we remove tg3_nvram_read_swab() and document what the
code is really doing.
