[ARM] Remove definition of MAX_DMA_CHANNELS to zero
Since we now only build arch/arm/kernel/dma.c on machine types which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS to 0 to indicate this - this definition becomes superfluous. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
