ACPI: x86: Add skip i2c clients quirk for Acer Iconia One 8 A1-840
The Acer Iconia One 8 A1-840 (not to be confused with the A1-840FHD which is a different model) ships with Android 4.4 as factory OS and has the usual broken DSDT issues for x86 Android tablets. Add quirks to skip ACPI I2C client enumeration and disable ACPI battery/AC and ACPI GPIO event handlers. Also add the "INT33F5" HID for the TI PMIC used on this tablet to the list of HIDs for which not to skip i2c_client instantiation, since we do want an ACPI instantiated i2c_client for the PMIC.
