samus: Add hook/hack to enable backlight PWM
The backlight controller EEPROM is not enabling PWM mode and
it is reloaded every time the backlight state is changed.
Since we no longer have signals indicating when the PCH is
enabling or disabling backlight this hack will read the
controller every second at runtime to determine if it needs
to enable PWM mode.
This should be removed with the next build when the EEPROM is
changed to enable PWM mode by default.
