dmaengine: hsu: refactor hsu_dma_do_irq() to return int
Since we have nice macro IRQ_RETVAL() we would use it to convert a flag of handled interrupt from int to irqreturn_t. The rationale of doing this is: a) hence we implicitly mark hsu_dma_do_irq() as an auxiliary function that can't be used as interrupt handler directly, and b) to be in align with serial driver which is using serial8250_handle_irq() that returns plain int by design.
