Dominic Clifton 6d5b44df7a Fix boot failure on Flip32+ Deluxe Acro.
The problem was the MPU6050 EXTI handler was not registered due to baro
detection taking the only callback handler slot.  When the MPU6050 EXTI
was configured the interrupt flag was never cleared which results in the
CPU being starved.
