console: Only print romstage messages with EARLY_CONSOLE enabled.

Browse Source 
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).
