Setting: Display: Adaptive Brighrness:  fix checkbox not showing correct value

problem:  checkbox is not showing correct value  because the kernel driver
 does not allow getting CABC values.

flaw: on boot, the database is restoring the value anyways thus causing
an inconsistant value everytime you try to go to setting

fix: use database to restore that setting instead of the inconsistancy
of kernel driver.
