mach-msm/semc: revert disabling als at kernel level on all mogami-board device
Users reported problems where brightness would stay at full even if changed in
settings. Will also be better for testing fixes for ALS if we keep if enabled
at kernel level instead we can echo 0.
To disable it on every boot create an init.d with the following....

echo 0 > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable
