zephyr: lazor: enable ADC
Enable ADC. Lazor uses ADC_0 channel 1, 2, and 3.
The channel 1 is scaled down VBUS through a 1/10 voltage
divider. The zephyr driver returns the exact voltage, which
is VBUS * 1/10.
The channel 2 is AMON_BMON voltage which is not enabled
until the charger task is setup.
The channel 3 is PSYS voltage which is zero. PSYS monitoring
is not enabled unless the process is in S0.
BUG=b:182398910
BRANCH=None
TEST=Tested on Lazor:
uart: ~$ adc
ADC_VBUS = 500 mV
ADC_AMON_BMON = 13 mV
ADC_PSYS = 0 mV
