6.6-stable review patch. If anyone has any objections, please let me know.

From: Hans de Goede hdegoede@redhat.com
[ Upstream commit 8f62ca9c338aae4f73e9ce0221c3d4668359ddd8 ]
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 ship with Android 4.4 as factory OS and have the usual broken DSDT issues for x86 Android tablets.
Add a quirk to skip ACPI I2C client enumeration for the 5V version to complement the existing quirk for the 9V version.
