ffb0845971 foboot-main: wip commit 
Now foboot-main has been proven to kind of work.  When it's loaded to
0x1a000, the recovery image is able to properly locate it and jump to
it.

What isn't yet working is USB, however we are confident that our image
is getting loaded properly, and other images load just fine, so it's a
start at least.

5b71eeea7d foboot-bitstream: tristate pulldown on evt board 
The EVT board has a pulldown, in case we want to do USB LS.  This causes
issues on some hubs, because they end up with weak pullups, which throws
off enumeration.

Set it to a tristate input, which fixes this behavior.
