Add GPIO for PCH SRTCRST#

Browse Source 
In case ctl decides to put it on a separate GPIO, he'll use PC7.  If
he doesn't, we can reclaim this GPIO.

Signed-off-by: Randall Spangler <rspangler@chromium.org>

BUG=chrome-os-partner:7576
TEST=gpioget; signals should be present.  PCH_SRTCRSTn should be 1.
