[PATCH 0/4] i.MX8M: Add SNVS support

[Sascha Hauer]

This series adds support for Secure Non Volatile Storage (SNVS) to
i.MX8M.

The driver itself already exists for i.MX6, so we only need to add the
missing pieces and enable it in the config.

With this the SNVS is available as /dev/snvs. On i.MX8M its size is 16
bytes and the values are preserved over reset.
