lynxpoint: Add new GPIO interface for Lynxpoint-LP
The low power variant of the chipset introduces a completely
new interface to the GPIOs.
This is a 1KB region and so needs to be moved as well so it does
not conflict with other IO regions.
Also expose the gpio_get functions to ramstage and move the
prototypes to pch.h so they can be used for both GPIO interfaces.
