Clevo started using OZ711LV2 for the SD card reader around the time of
making its TGL boards. Without the driver, CPUs don't go to power states
lower than C2 due to LTR not being programmed. After enabling the driver
the CPU will go to C8 while the system is idle, giving significant power
savings if the system is left on battery power.
There is another issue with RPL where it only goes to C6 instead of C8.
This may be due to the intel_idle driver in Linux (as of 6.5-rc6
mainline and 6.4.6 stable) not supporting RPL C-states.
- tgl: Started being used with the Gazelle 3060 variant
- adl: Used on all models
- rpl: bonw15 does not have an SD card reader

System76 EC since system76/ec@9ac513128ad9 detects if the keyboard is
white or RGB backlit via `RGBKB-DET#` at runtime. Remove the Kconfig for
the selection and update the ACPI methods for the new functionality.

Replace `CBFS_SIZE` with FMD files to declare regions and sizes. This
will be used to lock BIOS region (except SMMSTORE) on boot.
`CBFS_SIZE` was incorrectly set to 10 MiB, so this also corrects the
BIOS region size to match the FIT values.

Multiple users have requested to have the DMI values for product UUID
and serial number be populated. Enable the drivers so that we may set
them when flashing or updating firmware.
