Browse Source 
Misidentifications are still occurring on slow plug insert, so double
the debounce time.

BUG=chrome-os-partner:35633
TEST=Manual on Samus. Plug 1A Apple charger and verify detection is
correct. Test various plug speeds and verify detection is correct on all
but intentional slow plugs (first contact to fully plugged > 1s).
BRANCH=Samus
