platform/x86: x86-android-tablets: Add Nextbook Ares 8 data 

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. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().

Add support for manually instantiating the I2C devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.
