kernel: Disable CONFIG_DMA_PERNUMA_CMA by default

Browse Source 
This CMA memory allocation option only applies to NUMA
(Non-Uniform Memory Access) systems which are seldom
the kind of systems that OpenWRT address.

It is safe to assume that any system that need this
option would turn it on locally.
