Adds mount-matrix as an optional property to dt-bindings
for the bmg160 gyroscope as the driver reads this optional
property during probe.

Signed-off-by: Vishwas Rajashekar <vishwas.dev@vrajashkr.com>

The bmg160 driver reads an optional mount-matrix using
"iio_read_mount_matrix" in "bmg160_core_probe" and stores
this orientation data in "struct bmg160_data". As the "mount-matrix"
property is used by the driver, this change proposes to add it to
the corresponding dt-bindings.

Thank you for the feedback! I've extended the existing example in v2.
