Mike Rapoport (Microsoft) aec20f3aa6 mips: fix HIGHMEM initialization 
[ Upstream commit f171b55f14 ]

Commit 6faea3422e ("arch, mm: streamline HIGHMEM freeing") overzealously
removed mem_init_free_highmem() function that beside freeing high memory
pages checked for CPU support for high memory as a prerequisite.

Partially restore mem_init_free_highmem() with a new highmem_init() name
and make it discard high memory in case there is no CPU support for it.
