ACPI: x86: Add skip i2c clients quirk for Lenovo Yoga Book X90
[ Upstream commit 1a1e7540cf501dd5c8b57a577a155cdd13c7e202 ]
The Lenovo Yoga Book X90 is a x86 tablet which ships with Android x86
as factory OS. The Android x86 kernel fork ignores I2C devices described
in the DSDT, except for the PMIC and Audio codecs.
As usual the Lenovo Yoga Book X90's DSDT contains a bunch of extra I2C
devices which are not actually there, causing various resource conflicts.
Add an ACPI_QUIRK_SKIP_I2C_CLIENTS quirk for the Lenovo Yoga Book X90
to the acpi_quirk_skip_dmi_ids table to woraround this.
The DSDT also contains broken ACPI GPIO event handlers, disable those too.
