drivers/uart8250mem: Check for zero base address
Before adding a new UART to the coreboot/lb table, verify that it has a non-zero base address. This is consistent with all other functions that use the uart_platform_base() function. This was tested on google/kahlee by using an invalid UART number and forcing the base address to 0. Execution was able to complete through depthcharge and into the OS.
