Andy Shevchenko fed2574b3c dw_dmac: introduce software emulation of LLP transfers ...

Some controllers have the reduced functionality where the LLP multi block
transfers are not supported. This patch introduces a support of such
controllers. In case of memory copy or scatter-gather lists it emulates LLP
transfers via bunch of the regular single block ones.
