[PATCH 6/7] x86/boot: Exclude early_serial_console.c if can't use it.

Removes early_serial_console.c code if we don't have the config option that enables it (EARLY_PRINTK). When disabling this code, make early_serial_base a constant 0 to allow the compiler to optimize away the code that checks for early_serial_base. Signed-off-by: Joe Millenbach Signed-off-by:
