dmaengine: ti: edma: make the loop condition simpler in edma_probe()

When i == ecc->num_tc, the edma_probe() calls
of_parse_phandle_with_fixed_args() and breaks from the loop regardless
of the return value. Since neither the returned value nor the output
argument tc_args is used, set i < ecc->num_tc as the loop condition.
