x86, setup: reorganize the early console setup
Separate early_serial_console from tty.c This allows for reuse of early_serial_console.c/string.c/printf.c/cmdline.c in boot/compressed/. -v2: according to hpa, don't include string.c etc -v3: compressed/misc.c must have early_serial_base as static, so move it back to tty.c for setup code Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4C568D2B.205@kernel.org> Signed-off-by: H.
