[PATCH 1/2] iio: gyro: bmg160_spi: add of_match_table

[Jun Yan]

Add of_match_table to bmg160_spi driver.

This fixes automatic driver loading by userspace
When using the device tree and the driver is built
as a module, devices can be probed.

[Jun Yan]

BMI088 is missing from the of_match_table. Let's complete it.
