[PATCH v3 4/5] arm64: dts: rk3399-pinephone-pro: Add mount-matrix for magnetometer

[Rudraksha Gupta via B4 Relay]

From: "Leonardo G. Trombetta" <lgtrombetta at gmx.com>

After experimenting with the magnetometer on the Pinephone Pro I found
out the mount-matrix currently reported by the AF8133J driver is just
the identity matrix (no rotation), which is wrong. It would seem to me
that there is currently no `mount-matrix` info and that's why the driver
reports a trivial answer. As far as I can tell from my tests, a 90
degree clockwise rotation in the XY plane would align it properly.
