ARM: PL08x: fix array overflow in dma_set_runtime_config()
If maxburst was passed in as zero, we would overflow the burst_sizes[]
array. Fix this by checking for this condition, and defaulting to
single transfer 'bursts'.
Improve the readability of the loop using a for() loop rather than
a while() loop with the iterator initialized far from the loop.
