iio: cros_ec: Set Gyroscope default frequency to 25Hz

commit 336306790b2bbf7ce837625fa3b24ba724d05838 upstream.

BMI160 Minimium gyroscope frequency in normal mode is 25Hz.
When older EC firmware do not report their sensors frequencies,
use 25Hz as the minimum for gyroscope to be sure it works on BMI160.
