Subject: [PATCH] bmi160_main:Make the internal interface conditional on
 PX4_SPIDEV_BMI

   px4fmuv2 had PX4_SPIDEV_BMI defined, for the v3 cmake, but never
   provided a Chip select decoded by PX4_SPIDEV_BMI. PX4_SPIDEV_BMI
   has been removed from V2, but PX4_SPIDEV_EXT_BMI still remains
   and has a chip select assigned to it.
