You need to call apbuart_register() before you can open /dev/apbuart1.

There is no need to recompile RTEMS to use the leonuart driver.
Just compile and link the driver with your application and call
leonuart_register().

Yes, but it won't have any effect if the driver is using polled I/O.
In any case it will not change the size of the hardware fifo.
