dmaengine: coh901318: fix integer overflow when shifting more than 32 places
Currently U300_DMA_CHANNELS is set to 40, meaning that the shift of 1 can
be more than 32 places, which leads to a 32 bit integer overflow. Fix this
by using 1ULL instead of 1 before shifting it. Also add braces on the
for-loop to keep with coding style conventions.
