[PATCH v2] dmaengine: sun4i: fix invalid argument

Mason

From: Marc Gonzalez <marc_gonzalez@sigmadesigns.com>

The "pchans_used" field is an unsigned long array.

for_each_clear_bit_from() expects an unsigned long pointer,
not an array address.

$ make C=2 drivers/dma/sun4i-dma.o
CHECK drivers/dma/sun4i-dma.c
drivers/dma/sun4i-dma.c:241:9: warning: incorrect type in argument 1 (different base types)
drivers/dma/sun4i-dma.c:241:9: expected unsigned long const *p
drivers/dma/sun4i-dma.c:241:9: got unsigned long ( *<noident> )[1]
