Subject: [PATCH] dt-bindings: iio: imu: mpu6050: Improve i2c-gate disallow list

Before all supported sensors except for MPU{9150,9250,9255} were not
allowed to use i2c-gate in the bindings which excluded quite a few
supported sensors where this functionality is supported.

Switch the list of sensors to ones where the Linux driver explicitly
disallows support for the auxiliary bus ("inv_mpu_i2c_aux_bus"). Since
the driver is also based on "default: return true" this should scale
better into the future.
