mm: define MADV_FREE for some arches
Most architectures use asm-generic, but alpha, mips, parisc, xtensa
need their own definitions.
This patch defines MADV_FREE for them so it should fix build break
for their architectures.
Maybe, I should split and feed piecies to arch maintainers but
included here for mmotm convenience.
