the SNVS using the SCU API.
The module also adds some commands:
- snvs_cfg: Configure the SNVS HP and LP registers
- snvs_dgo_cfg: Configure the SNVS DGO bloc if present (8QXP)
- tamper_pin_cfg: Change the configuration of the tamper pins
- snvs_clear_status: Allow to write to LPSR and LPTDSR to clear
status bits
