[ARM] dma: rejig DMA initialization
Rather than having the central DMA multiplexer call the architecture specific DMA initialization function, have each architecture DMA initialization function use core_initcall(), and register each DMA channel separately with the multiplexer. This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.) Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
