The Vexia EDU ATLA 10 tablet comes in 2 different versions with significantly different mainboards. The only outward difference is that the charging barrel on one is marked 5V and the other is marked 9V. Both are x86 ACPI tablets which ships with Android x86 as factory OS. with a DSDT which 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(). Extend the existing support for the 9V version by adding support for manually instantiating the I2C devices which are actually present on the 5V version by adding the necessary device info to the x86-android-tablets module.
