cyan/strago: disable Ambient Light Sensor device 

No devices are connected to i2c4 bus on
both strago and cyan board.
Hence disabling the ALS platform data.
This will fix the i2c4 timeout issue and
also help in boot time optimization.

Removed unused macros.

BUG=None
BRANCH=chrome-os-partner:41934
TEST=After booting to kernel, i2c4 timeout
error message should not appear in dmesg.
