DMA: shdma: switch DT mode to use configuration data from a match table
This facilitates DMAC DT support by eliminating the need in AUXDATA and
avoiding creating complex DT data. This also fits well with DMAC devices,
of which SoCs often have multiple identical copies and it is perfectly
valid to use a single configuration data set for all of them.
