brcm47xx: update early printk patches
Early printk was disabled because it caused hangs on some devices, the old patches were using the CFE console now we use the normal serial console, it is at a constant address.

-Subject: [PATCH 6/6] MIPS: BCM47xx: Remove CFE console
-
-Do not use the CFE console. It causes hangs on some devices like the
-Buffalo WHR-HP-G54.
