mb/google/sarien: Configure both GPP_H12 and GPP_H13 for SSD on Arcada
Currently, Arcada only supports D3hot during S0iX and there is leakage
power around 5~10mW depending on SSD vendors.
To support D3cold for SSD during S0iX, one MOSFET will be added on DVT2
and two GPIOs are required to be configured.
GPP_H13 is to control SSD_SCP_PWR_EN(power enable) and GPP_H12 is to
control SSD reset.
BUG=b:130741066
TEST=Measure SSD power during S0iX from Arcada(DVT2)
