[MinnowBoard] MInnowboard MAX/Turbot LSE headers

[John 'Warthog9' Hawley]

I wouldn't use the 3.3V for more than a couple hundred mA, but it would
be solid to treat it as a reference voltage from the LSE.  the 5V you
should be able to pull ~1A without too much issue, beyond that I'd
suggest providing external power.
