• I've searched for existing issues and didn't find any that matched.

Description

The machine.UART.irq entry on the public docs has the following arguments:
UART.irq(trigger, priority=1, handler=None, wake=machine.IDLE)

However, looking at extmod/machine_uart.c, and in practice, machine.UART.irq behaves more like:
UART.irq(handler=None, trigger=0, hard=False).
Note that the position of handler is wrong, priority and wake should be removed and hard needs to be added.

I would like to update docs/library/machine.UART.rst to reflect the correct arguments.
But maybe other platforms handle machine.UART.irq differently, and I only use MicroPython on STM32 devices.

Please, let me know if that's the case and, if not, I'll proceed to fix and create a merge request.
