Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module.
