jacuzzi: disable adc after board version detected
This CL reverts the change in CL:1416074 for devices without POGO pin.
To reduce power consumption, we should to disable adc module if it's
only used by one-off board/sku id init.
For devices with pogo, keep adc enabled for device type detection.
BUG=b:138180455
TEST=dut-power in G3, verify that power consumption is lower
