ACPI: video: Add "vendor" quirks for 3 Lenovo x86 Android tablets
Like the Xiaomi Mi Pad 2 these 3 Lenovo x86 Android tablet models also
use a TI LP8557 backlight controller in direct I2C brightness register
control mode.
Add "vendor" quirks for these 3 models to disable the non-working
native / acpi_video backlight devices.
