Try to avoid dereferencing the DMA engine's channel struct in these
platform helpers; instead, pass a pointer to the channel data into
get_signal(), and the returned signal number to put_signal().

There is an in-tree user of this interface now, so it needs to be fixed
as part of this patch:
]$ grep -r pl080_get_signal .
./mach-spear6xx/spear6xx.c:	.get_signal = pl080_get_signal,
./plat-spear/include/plat/pl080.h:int pl080_get_signal(struct
pl08x_dma_chan *ch);
./plat-spear/pl080.c:int pl080_get_signal(struct pl08x_dma_chan *ch)
./mach-spear3xx/spear3xx.c:	.get_signal = pl080_get_signal,

I can't do that at the moment because that's come in during this merge
window and these patches are based on v3.4 at the moment.  In other
words, for the purposes of this series, the above simply does not exist.
