Revert "staging: octeon: remove typedef in enum cvmx_spi_mode_t"

This reverts commit 7bebd832.

The patch series that removed typedefs from the octeon driver was not
actually built properly, and broke the build (it's hard to test-build
this driver for some reason.)  Remove them all at this point in time to
make sure the build works properly.
