storm: deassert SW_RESET signal at startup
The proto0.2 hardware connects gpio26 (sw reset) to the ethernet
switch reset pit. The output stays low (or high-z) after power up,
which holds the switch in reset. Deassert the signal at startup on
hardware rev 1 and later.
BUG=chrome-os-partner:31780
TEST=with this patch applied, when proto0.2 boots, the ethernet
switch's LED blink once, as was the case with proto0.
