link: enable +5V always-on at startup
The EVT boards will have an enable signal for the +5V always-on rail
connected to GPIO PK4.
Just turn it on at startup to ensure that EVT boards will run out of the
box with the current EC firmware.
(PK4 is a test point on proto-1 board, this should be harmless).
We can later implement fancier power saving scheme by enabling it only
when we enter S3.

BUG=chrome-os-partner:9284
TEST=boot Linux kernel on Link proto-1 and Link-1 proto-1 reworked with
+5V Always-on enable on PK4.
