Damien George 0975255f86 stm32/uart: Suppress additional RX idle IRQs on F4/L1. ...

These MCUs only clear the RX idle IRQ if the data register is read, which
won't occur if the only IRQ is the RX idle IRQ (because then reading and
discarding the DR may lead to lost data).

To work around this, explicitly suppress the RX idle IRQ so that it's only
passed through to the Python callback once.
