make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.
This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.
The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.
uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.
