Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
These drivers appear to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

This patch adds property 'rockchip,path-map' for path mapping.

e.g.

"rockchip,path-map = <3 2 1 0>" means the mapping as follows:

  path0 <-- sdi3
  path1 <-- sdi2
  path2 <-- sdi1
  path3 <-- sdi0
