OPT3001: Support MOTIONSENSE_CMD_SENSOR_[OFFSET|RANGE] for calibration.

1. The original driver of OPT3001
  a. didn't support to process the command of offset.
  b. implemented command of range to setter/getter of Range Number Field
     of chip.
But reffering to cros_ec_light_prox.c from linux kernel side, these two
commands are actually leveraged for in_illuminance_calib[bias|scale]
and these calibration factors should be applied into raw lux value read
from the chip.

2. Move ALS in Poppy / Soraka boards from ALS_TASK to MOTIONSENSE_TASK.

3. Mofify parameters of ALS in Reef board in order to adapt changes
here.

BUG=b:69236269
BRANCH=none
TEST=Manually test on the DUT.
