iio: ad_sigma_delta: Implement a dedicated reset function
commit 7fc10de8d49a748c476532c9d8e8fe19e548dd67 upstream.
Since most of the SD ADCs have the option of reseting the serial
interface by sending a number of SCLKs with CS = 0 and DIN = 1,
a dedicated function that can do this is usefull.
Needed for the patch: iio: ad7793: Fix the serial interface reset
