Fix these errors:

 arch/mips/cavium-octeon/executive/cvmx-pko.c:489:7: error: this statement may fall through [-Werror=implicit-fallthrough=]
 arch/mips/bcm63xx/dev-flash.c:89:3: error: this statement may fall through [-Werror=implicit-fallthrough=]
 arch/mips/ath79/setup.c:155:17: error: this statement may fall through [-Werror=implicit-fallthrough=]
 arch/mips/ar7/setup.c:50:3: error: this statement may fall through [-Werror=implicit-fallthrough=]

These are the remaining errors in Linus' tree.

Again, not even tested, but pretty straight forward.
