iio: imu: fxos8700: fix incomplete ACCEL and MAGN channels readback
commit 37a94d86d7050665d6d01378b2c916c28e454f10 upstream.
The length of ACCEL and MAGN 3-axis channels output data is 6 byte
individually. However block only read 3 bytes data into buffer from
ACCEL or MAGN output data registers every time. It causes an incomplete
ACCEL and MAGN channels readback.
Set correct value count for regmap_bulk_read to get 6 bytes ACCEL and
MAGN channels readback.
