Several versions of DW DMAC have multi block transfers hardware
support. Hardware support of multi block transfers is disabled
by default if we use DT to configure DMAC and software emulation
of multi block transfers used instead.
Add multi-block property, so it is possible to enable hardware
multi

Changes for v6:
* Use "supported" as default state for "multi-block" property,
to keep old DTBs working. Pointed by Andy Shevchenko.
Changes for v5:
