driver: icm426xx: discard first data instead of sleeping
Sleeping when turning a sensor on/off is problematic when the
other sensor is running.
Replace sleeping by discarding first events until sensor is
stabilized.
BUG=chromium:1175757
BRANCH=hatch,nami,kukui,dedede,grunt,zork,octopus,volteer
TEST=turn sensor on/off when the other is running using cros-ec
iio devices
