mimxrt/machine_uart: Fix rx/tx buffer allocation bug.
The buffer would be reset on every call to `uart.init()`. If no sizes were
given, the buffer would be set to the default size 256. That made problems
e.g. with PPP. Also, the RX buffer was not stored at the UART object and
not visible to GC as being in use. Then a `gc.collect()` would eventually
free the buffer.
This commit fixes those issues, keeping the buffer size if not deliberately
changed and allocating new buffers only if the size was changed.
