machine: don't block the rp2xxx UART interrupt handler
...
Don't block forever if there's nothing to receive. On the other hand,
process the entire FIFO, not just a single byte.
This fixes an issue where the rp2350 would hang after programming through
openocd, where the UART0 interrupt would be spuriously pending.
