Gustavo Jose de Sousa c72dc9bd45 AP_InertialSensor: make single rotation on MPU9250 
The previous implementation made some boards apply two rotations to suit
their default orientation. That was happening because there was an
unconditional rotation being done (commented as "rotate for bbone
default").

This commit makes that unconditional rotation as a default rotation
instead and adjusts the former additional rotations to be single
rotations.

Gustavo Jose de Sousa 3dad768e8b AP_InertialSensor: log failure to initialize after max attempts on MPU9250 
This happens for example when you are trying to use an SPI speed that's
above the one supported by the sensor or the controller.

Gustavo Jose de Sousa 587471ab54 AP_InertialSensor: disable I2C on MPU9250 
As the datasheet says: "To prevent switching into I2C mode when using
SPI, the I2C interface should be disabled by setting the I2C_IF_DIS
configuration bit."

We also reset the sensor like PX4Firmware does for initializing the
MPU6000.  See: ee1d8cd770/src/drivers/mpu6000/mpu6000.cpp (L695)

Andrew Tridgell f831c16238 AP_InertialSensor: use fixed sensor sample times 
this uses fixed sample times for PX4 IMUs, rather than reported
timestamps. It avoids timing jitter caused by the over-sampling in
the PX4 drivers

Functor is not yet being used but let's make is macro fallback to the
previous Delegate implementation for easy of transition between the two.

Andrew Tridgell 007b01533d AP_InertialSensor: switched to 16g accel range for MPU9250

have seen clipping at 8g

Lucas De Marchi b292873304 AP_InertialSensor: fix starvation in L3G4200D 
The main thread would always be blocked on the semaphore to read the
data from accelerometer and gyroscope. Especially if we have a slow
update of these values in _accumulate() due to the I2C transfer function
taking too much time: the timer thread would never give up the CPU,
causing starvation on the main thread.

This fixes the issue by reducing the critical region using a flip-buffer
so _accumulate() can work on its own copy of the data. Now that the
critical region is smaller, also avoid the semaphore and use a spinlock
instead.
