armv7: Use same console initialization procedure for all ARM stages
Use same console initialization procedure for all ARM stages (bootblock, romstage, and ramstage): #include <console/console.h> ... console_init() ... printk(level, format, ...) Verified to boot on armv7/snow with console messages in all stages.
