power: smb5: Disable charger-hw ADC channels before reading USBIN_V

There could be a possible hardware coupling between USBIN_V channel
and other voltage based ADC channel which could lead to false
USBIN_OV interrupts. Fix this by disabling voltage based charger-hw
ADC channels before reading USBIN_V.
