mb/google/nissa/var/craaskov: Configure the external V1p05/Vnn/VnnSx
This patch configures external V1p05/Vnn/VnnSx rails for Craaskov
to follow best practices for power savings – untested though.
* Enable the external V1p05, Vnn, VnnSx rails in S0i1, S0i2, S0i3, S3,
S4, S5 , S0 states.
* Set the supported voltage states.
* Set the voltage for v1p05 and vnn.
* Set the ICC max for v1p05 and vnn.
