ARM: meson: serial: don't reset port on uart startup

When the uart startup entry is called, do not reset the port as this
could cause issues with anything left in the FIFO from a previous operation
such as a console write. Move the hardware reset to probe time and simply
clear the errors before enabling the port.

This fixes the issue where the console could become corrupted as there
where characters left in the output or output fifo when a user process
such as systemd would open/close the uart to transmit characters.

For example, you get:
    [    3.252263] systemd[1]: Dete

instead of:
    [    3.338801] systemd[1]: Detected architecture arm.
