console: Revise serial console configuration names.
The console drivers (especially serial drivers) in Kconfig were named in different styles. This change will rename configuration names to a better naming style. - EARLY_CONSOLE: Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE because it also supports non-serial) - CONSOLE_SERIAL: Enable serial output console, from one of the serial drivers. (Renamed from SERIAL_CONSOLE because other non-serial drivers are named as CONSOLE_XXX like CONSOLE_CBMEM) - CONSOLE_SERIAL_UART: Device-specific UART driver. (Renamed from CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped) - HAVE_UART_SPECIAL: A dependency for CONSOLE_SERIAL_UART. Verified to boot on x86/qemu and armv7/snow, and still seeing console messages in romstage for both platforms.
