yorp: add internal PUs for unused pins to prevent leakage current.
This CL adds internal PUs for unused pins on yorp in gpio.inc to prevent
leakage current. Please notice the test platform is yorp proto 1. Beside
PUs for strap-pins, the configuration of other pins might need to change
on yorp proto 2.
BRANCH=none
BUG=b:110170824
TEST=No build errors for npcx7 series. Adding PUs on strap-pins saves
~0.4mA at S0ix. Adding PUs on the other unused pin saves ~0.2mA at S0ix.
