"config ARCH_SPARSEMEM_ENABLE" exists in both arch/mips/Kconfig and

This results in warnings when a non-Cavium platform tries to select
ARCH_SPARSEMEM_ENABLE:
$ make lemote2f_defconfig ARCH=mips
warning: (LEMOTE_FULOONG2E&& LEMOTE_MACH2F) selects ARCH_SPARSEMEM_ENABLE which has unmet direct dependencies (CPU_CAVIUM_OCTEON)

# configuration written to .config

Proposed workaround is to use a Cavium-specific config option which
"select"s the desired options.

A cleaner patch for this was already done here:
