brcm47xx: add initial support for kernel 3.8 

This contains the following new bigger changes:
 * new partition parser which still could lake some features or have bugs
 * new nand flash driver
 * using physmap-flash flash driver for parallel flash
 * some changes to the serial flash driver

With these changes OpenWrt starts using more of the mainline flash drivers.

Subject: [PATCH 4/6] MIPS: BCM47xx: Setup and register serial early
Swap the first and second serial if console=ttyS1 was set.
Set it up and register it for early serial support.
This patch has been in OpenWRT for a long time.

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.

commit fa0879e37b59e8e3f130a30a9e6fa515717c5bdd
Author: Stefan Hajnoczi <stefanha@gmail.com>
Date: Mon Jan 21 01:17:22 2013 +0000
net: split eth_mac_addr for better error handling
When we set mac address, software mac address in system and hardware mac
address all need to be updated. Current eth_mac_addr() doesn't allow
callers to implement error handling nicely.
This patch split eth_mac_addr() to prepare part and real commit part,
then we can prepare first, and try to change hardware address, then do
the real commit if hardware address is set successfully.

configuration. The cfe_env.c file uses a different method way to read
out the configuration than the in kernel cfe config reader.
