ARMv7: Clean up console code

- Guard console_init() with CONFIG_EARLY_CONSOLE in bootblock
 - Don't initialize console twice in the bootblock
 - remove printk in memory init that would mess up the UART
 - unconditionally run console_init() in romstage, as it is
   also unconditionally run in the bootblock.
