  • initial ICM426xx support
  • WIP
  • needs testing
  • needs target definitions separately PR'd
  • may need fixes
  • may need cleanup (especially GYRO_HARDWARE_LPF_* options)

This code is ported from Betaflight. Thanks to Betaflight team and GPL licensed opensource.

Massive thanks to @Peck07 for investigting and fixing some pre-existing failed works.

Since this is not defined as a dual gyro quad, and there is no GYRO_2, you cannot use defines for GYRO_1

Don't need MPU6500 defines, and probably don't need the MPU6000 defines since pretty certain this is an ICM42xxxp specific target and FC

please see #890 (comment)

i.e. ICM42688P_EXTI_PIN is not a valid define in source-code. use GYRO_1_EXTI_PIN or MPU_INT_EXTI instead.
