The Acer Iconia One 7 B1-750 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 Acer Iconia One 7 B1-750'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 Acer Iconia One 7 B1-750
to the acpi_quirk_skip_dmi_ids table to woraround this.
The DSDT also contains broken ACPI GPIO event handlers, disable those too.
