it83xx: adc: interrupt is used
We don't need to loop and waiting ADC's data valid flag
after the change was made.
Signed-off-by: Dino Li <dino.li@ite.com.tw>
BRANCH=none
BUG=none
TEST=1. We build a EC binary for PD EVB (declared two ADC channels
for VBUS measurement of PD task and priority is highest)
2. Use console command "adc" continually to read ADC channels
and check if any error.
