While the 8250 compatible serial port driver is primarily useful on x86 systems because it works with the legacy x86 com ports, some devices which aren't x86 based have 8250 compatible UARTs as well. This change renames the CONFIG_X86_SERIAL_CONSOLE option to the more general and direct CONFIG_8250_SERIAL_CONSOLE and fixes up the dependencies so that non-x86 systems can enable the driver, although it will default to on on x86 and off otherwise. Also, the default IO port address that's added to the sysinfo structure on x86 and which is intended to be overwritten by a value in the coreboot tables is not used on ARM. That variable is adjusted so that it's more clear it's a default value, and made dependent on x86 since that's the only place its value is actually used. BUG=None TEST=With this and other changes, built for an ARM board which has an ns16550 (and essentially 8250) compatible UART. Built for pit and for link.
