soc/amd/stoneyridge/southbridge.c: Remove configure_stoneyridge_uart

Browse Source 
The GPIO programming of configure_stoneyridge_UART() can be done by the early
GPIO table, AOAC enabling was already removed. So  configure_stoneyridge_uart()
became redundant. Remove procedure  configure_stoneyridge_uart().

BUG=b:74258015
TEST=Build and boot kahlee, observing serial output does not changes from
previous serial output.
