This makes sure the DMA40 driver will also work on the oldest
silicon revisions that have the on-chip memory on another location
in the DB8500 and also requires explicit suspend before starting
or resuming a logical channel.

This follows on the patch to allocate LCLA dynamically: the
on-chip memory is needed for other things so now that that
we're using it dynamically we can remove the LCLA resource
altogether and free up some ESRAM memory.

This completes the DMA40 support with the platform-specific
configuration for U8500/DB8500.

Split up all the hardware register definitions previously found in
hardware.h into per-SoC files db8500-regs.h and db5500-regs.h. Rename a
couple of macros to prepare for sharing code between the variants.
