The Lenovo Yoga Tablet 2 Pro 1380F/L is a x86 ACPI tablet which ships with
Android x86 as factory OS. 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.
