mainboard/google/kahlee: Update WP to active low

The WP signal to the AP isn't inverted as it is on other platforms, so
it was reporting incorrectly.  Change the ACPI table to be active low,
and invert the signal when reporting it to everything else.

BUG=b:74946358
TEST=Boot grunt with battery inserted, WP signals both report 1.  Remove
battery, WP_CUR reports 0, WP_BOOT still reports 1.
