dma: SG elem lists replaced with arrays

Multiple alloctions of SG elements linked as a list
replaced with single allocations of arrays.

- The code flows (esp. cleanup-on-error) are simplified,

- number of 64bytes chunk allocations reduced from 18 to 12 for
  example very basic topology, no increase in other areas
  (2-period sgls still fit),

- more efficient allocation for host page tables on legacy platforms;
  instead of going from a desc array to the list that is copied to
  another list, there is just a single allocation of array moved
  to the destination component.
