Ben Dooks 00661dd855 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.
