char: xilinx_uartlite: Don't reset from init
This refresh of the device state is intended to be a reset side effect. Move it to a proper reset handler rather than do it at init time. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
