MIPS: Alchemy: remove dbdma compat macros
Manuel Lauss [Tue, 13 Oct 2009 18:22:34 +0000 (20:22 +0200)]
Remove dbdma compat macros, move remaining users over to default
queueing functions and -flags.

(Queueing function signature has changed in order to give
 a build failure instead of silent functional changes due
 to the no longer implicitly specified DDMA_FLAGS_IE flag)
