[ Upstream commit a5cb0695c5f0ac2ab0cedf2c1c0d75826cb73448 ]
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.
