eve: Ignore VCC1_RST status bit when determining reset cause

Browse Source 
The EC on Eve has VCC1_RST connected to 3.3DSW which drops when
resetting for recovery.

Since I need this to work on current boards treat Eve the same as
Wheatley and use the workaround that always reports reset-pin
instead of power-on status.

BUG=chrome-os-partner:61028
BRANCH=none
TEST=successfully enter recovery mode on eve with the keyboard
