iio: adc: ad4062: Switch from struct i3c_priv_xfer to struct i3c_xfer

Commit 9904232ae30bc ("i3c: drop i3c_priv_xfer and i3c_device_do_priv_xfers()")
currently in the i3c/for-next tree removes the deprecated
struct i3c_priv_xfer and i3c_device_do_priv_xfers().

Switch to struct i3c_xfer and i3c_device_do_xfers(..., I3C_SDR)
now rather causing a build issue when both trees are merged.
