[PATCH V3 4/6] iio: accel: bmi088: Add support for bmi085 accel

[LI Qingwu]

Add supports for BMI085, an Inertial Measurement Unit,
with an accelerometer and gyroscope.
The commit adds the accelerometer driver for the SPI interface.
The gyroscope part is already supported by the BMG160 driver.
Different from BMI088, the BMI085 accelerometer has the range of
+/-2, 4, 6, and 8g.
