(1/6) bcm57xx: init from diag

I've been working to finish up the bcm57xx module package nbd
posted a few months ago.  I am no expert, just had some spare
time and some motivation.  Here is the background:

https://dev.openwrt.org/ticket/2744

This first patch disables the bcm57xx gpio setup in broadcom-diag.
The switch needs to be initialized by the driver so the driver can
then reset the switch ASAP.  If the switch isn't reset quickly enough,
it will forward packets between the WAN and LAN, which will cause
problems with modems that only allow one mac to access the internet.

Tested on wrt350n.
