driver/tcs3400: disable ADC & oscillator between reads
Disabling ADC and oscillator after servicing the interrupt
not only saves power, but it assures the next light sample gathered
will be based on a single again and atime setting. Without disabling
ADC and oscillator, part of the next sample was getting sampled at
one again and atime setting, but part of that sample was getting
sampled using a different again or atime setting in cases where
the saturation compensation mechanism changed again or atime.
BUG=b:134188019
BRANCH=master
TEST=Flash and boot flapjack, verify that ALS and RGB sensors
are still generating data (I used alslog patch and enabled
logging in EC console via "alslog" command).
