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.
