soc/intel/apollolake: Don't use pulldowns in standby state for 1.8/3.3V pins.
These pins should not have pull downs configured in standby state as that
can cause contention on the termination circuitry and lead to incorrect
behavior as per Doc# 572688 Gemini Lake Processor GPIOTermination
Configuration.
Furthermore, some of these pins were configured with normal termination
of None which would as per above mentioned document lead to a standby
termination of None anyways.
Instead of pull downs, use the IOSSTATE setting for driving low
via the Tx mode.
BUG=b:79874891, b:79494332, b:79982669
BRANCH=None
TEST=Flashed image and booted to OS on Yorp. Touchscreen does not
consume power in suspend state.
