Add an accelerometer orientation quirk for the Yours Y8W81 8" tablet.
For future reference: this tablet has the same case and mostly the same
internals as the Chuwi Vi8. Both seem to be from an ODM called inet-tek.
Both are labelled: "INET-I86M-REVxx" on the PCB, with the Chuwi Vi8 being
REV03 (and having a ALC5640 audio codec) and the Yours Y8W81 being REV21
(and having a ALC5651 audio codec).
