Merge ACPI backlight driver changes, ACPI changes related to PCI and
ACPI documentation changes for v5.20-rc1:

 - Use native backlight on Dell Inspiron N4010 (Hans de Goede).

 - Use native backlight on some TongFang devices (Werner Sembach).

 - Drop X86 dependency from the ACPI backlight driver Kconfig (Riwen
   Lu).

 - Shorten the quirk list in the ACPI backlight driver by identifying
   Clevo by board_name only (Werner Sembach).

 - Remove useless NULL pointer checks from 2 ACPI PCI link management
   functions (Andrey Strachuk).

 - Fix obsolete example in the ACPI EINJ documentation (Qifu Zhang).

 - Update links and references to _DSD-related documents (Sudeep Holla).
