staging: mrst: overlay: Use set_memory_wc() instead of vmap()

x86 has set_memory_*() API so no need to vmap(). Also change from UC
to WC to make register updates, coeff tables in particular, more
efficient. There's a wmb() already in the code, and AFAICS that
should be enough to flush the WC buffers.
