[ Upstream commit 0e289012b47a2de1f029a6b61c75998e2f159dd9 ]
Same SSI device may be used in different dai links, by only having one dma struct in rsnd_ssi, after the first instance's dma config be initilized, the following instances can no longer configure dma, this causes issue, when their dma data address are different from the first instance.
