Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for

NOTE:
We don't touch any aperture configuration in this patch series. So we
don't switch any devices between IOC and non-IOC AXI ports on any board.
It can be done later if it is required.

ZONE_HIGHMEM case.
(BTW: current ARC dma_noncoherent_ops implementation also has same
problem if IOC and HIGHMEM are enabled.)

In this RFC only hsdk.dts changes are shown to reduce patch size.

This patch at least shouldn't break anything for current users (which use
it in single slot mode)
Moreover we tested this dual-slot implementation and don't catch any problems
(probably yet) except bus performance decrease in dual-slot mode (which is
quite expected).
