uart: add resume method and enable it for attachments on the most common
x86 buses
Otherwise the uart hardware could be in such a state after the resume
where IER is cleared and thus no interrupts are generated.
This behavior is observed and tested with QEMU, so I am comitting this
change to help with my debugging.
There has been no feedback from users of serial ports on real hardware.
