Jisheng Zhang 29d35f0b53 serial: 8250_dw: fall back to poll if there's no interrupt ...

[ Upstream commit 22130dae0533c474e4e0db930a88caa9b397d083 ]

When there's no irq(this can be due to various reasons, for example,
no irq from HW support, or we just want to use poll solution, and so
on), falling back to poll is still better than no support at all.
