GPIO/IOEX/eSPI: Give different IO signals unique values
There are 3 different IO signal types used by the EC.
Ensure they each use a unique range of values so we can tell them apart.
1) Local GPIO => 0 to 0x0FFF
2) IO expander GPIO => 0x1000 to 0x1FFF
3) eSPI virtual wire signals => 0x2000 to 0x2FFF
BUG=b:138600691
BRANCH=none
TEST=IO expander signals still work on Trembyle
