iio: imu: fxos8700: fix incomplete ACCEL and MAGN channels readback 



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.
