mode_cardemu: Move GPIO detection to IRQ, use ring buffer for UART RX
...
We don't want to call into the bulk of card_emu.c from interrupt
context, so let's introduce a ring buffer as a softwre-FIFO between
the USART receiving a byte and the processing of that byte in
card_emu.c, which is then performed from the main loop outside
interrupt context.

mode_cardemu: update_fidi just needs to execute
...
the actual translation of the Fi/Di values to the divider is
already made, we just need to update the USART divider here.

mode_cardemu: Proper enabling/disabling of USART IRQ sources
...
we always have to disable all intrerrupts that we don't want to be
enabled
