console: Only print romstage messages with EARLY_CONSOLE enabled.
Revise console source file dependency (especially for EARLY_CONSOLE) and interpret printk/console_init according to EARLY_CONSOLE setting (no-ops if EARLY_CONSOLE is not defined). Verified to boot on x86/qemu and armv7/snow. Disabling EARLY_CONSOLE correctly stops romstage messages on x86/qemu (armv7/snow needs more changes to work).
