ACPI: LPSS: Add dmi quirk for skipping _DEP check for some device-links
The iGPU / GFX0 device's _PS0 method on the ASUS T200TA depends on the
I2C1 controller (which is connected to the embedded controller). But unlike
in the T100TA/T100CHI this dependency is not listed in the _DEP of the GFX0
device.
This results in the dev_WARN_ONCE(..., "Transfer while suspended\n") call
in i2c-designware-master.c triggering and the AML code not working as it
should.
This commit fixes this by adding a dmi based quirk mechanism for devices
which miss a _DEP, and adding a quirk for the LNXVIDEO depending on the
I2C1 device on the Asus T200TA.
