Updated bcm63xx support

Hi Ralf, Maxime,

The following patch series updates the linux-bcm63xx tree with the following changes :

1: use gpiolib instead of the old GENERIC_GPIO API
2 and 3: add new board definitions that OpenWrt users have been able to run a kernel on
4: register a fallback SPROM for b43 to work
5 and 6: fix two variables that were not correctly zero initialized (from Maxime)
7 : fix typo in the CPU frequency print
8 : update defconfig with gpiolib support
9 : enable SSB support in the defconfig
10: fix compilation failure of the Ethernet MAC driver

Thanks.

Best regards, Florian Fainelli
