Revert "MIPS: Add custom serial.h with BASE_BAUD override for generic kernel"
This reverts commit c8ec2041f549e7f2dee0c34d25381be6f7805f99. There's no more need to set BASE_BAUD to 0 to make earlycon work properly on DTS-based boards since such cases were handled in commit 182ead3e418a ("earlycon: Remove hardcoded port->uartclk initialization in of_setup_earlycon"). earlycon no longer initializes port->uartclk with a value of BASE_BAUD * 16 when starting from FDT/OF.
