Add LOW_POWER_ hints for gs101 devices

Add LOW_POWER_LITTLE_CLUSTER_{50,60,70,80,90} and
LOW_POWER_CPU_{50,60,70,80,90} to match what is already present for
Pixel 3, 4 and 5.

Because of the presence of a MID cluster, we also add a new set of
hints LOW_POWER_MID_CLUSTER_{50,60,70,80,90}.

See go/powerbrain-cpu-gs101 for explanation on the selected
frequencies.

Bug: 151080800
Bug: 188770301
Test: Make and flash, use a dev version of Turbo to set a hint
