iio: imu: bmi270: fix initial sampling frequency configuration

In the bmi270_configure_imu() function, the accelerometer and gyroscope
configuration registers are incorrectly written with the mask
BMI270_PWR_CONF_ADV_PWR_SAVE_MSK, which is unrelated to these registers.

As a result, the accelerometer's sampling frequency is set to 200 Hz
instead of the intended 100 Hz.

Remove the mask to ensure the correct bits are set in the configuration
registers.
