From: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx>
Some of them were pointless because CONFIG_CAVIUM_RESERVE32 is now always
defined, some were not enough (Yu Zhao reported
"Failed to allocate CAVIUM_RESERVE32 memory area" error).
Removing the directives allows for compiler coverage of RESERVE32 code and
replacing one of [always-true] "ifdef" with a compiler conditional fixes
the [cosmetic] error message.
