powerpc: Rework dma-noncoherent to use generic vmalloc layer
This patch rewrites consistent dma allocations support to use vmalloc
layer to allocate virtual memory space from vmalloc pool and get rid
of CONFIG_CONSISTENT_{START,SIZE}.
This greatly simplifies the code by effectively removing a custom
allocator we had for virtual space.
