MIPS: Octeon: drop dependency on CONFIG_HOLES_IN_ZONE
CAVIUM_OCTEON_SOC configuration selects HOLES_IN_ZONE option to cope with memory crashes that were happening in 2011. This option effectively aliases pfn_valid_within() to pfn_valid() when enabled and hardwires it to 1 when disabled. The check for pfn_valid_within() is only relevant in case the memory map may have holes or undefined struct page instances inside MAX_ORDER chunks. Since 2011 memory management initialization in general and memory map initialization particularly became much more robust so the check for pfn_valid_within() is not required on Octeon even despite its, hmm, unusual memory setup. Remove the selection of HOLES_IN_ZONE by CAVIUM_OCTEON_SOC and drop the HOLES_IN_ZONE configuration option entirely as Octeon was the only MIPS platform to use it.
