From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit f38312c9b569322edf4baae467568206fe46d57b ]

The Nextbook Ares 8 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 (the Android x86
kernel fork ignores I2C devices described in the DSDT).

Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the
acpi_quirk_skip_dmi_ids table to woraround this.
