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,
