tty: serial: lpuart: avoid report NULL interrupt
The current driver register irq in .startup() and free the irq in
.shutdown(), then user will see the NULL interrupt output from
'cat /proc/interrupts' after the uart port test completed:
...
41: 515 0 0 0 GICv3 257 Level fsl-lpuart
42: 2 0 0 0 GICv3 258 Level
...
It is better to register all the irqs during probe function via devm_request_irq()
to avoid to call free_irq().
