it83xx/adc: adjust ADC read timeout to 1ms.
Voltage comparator has about 73us conversion time, and ADC read
channel has about 122 us conversion time.
ADC engine will convert each channel at a time (comparators and
ADC read channel) and current timeout setting is 248us, so we might
have a chance to trigger timeout if converting two comparators while
EC starts ADC read channel.
This change increased timeout to 1ms.
BUG=b:164256608
BRANCH=none
TEST=Verified that running 'ectool temps all' without error
on drawcia x200.
