NXP BBNSM (Battery-Backed Non-Secure Module) serves as non-volatile
logic and storage for the system. it provides some similar functions
like RTC and ON/OFF support as previous SNVS module found on legacy
i.MX SoCs. The BBNSM is replacement of previous SNVS module, and more
likely it will be used on all the future i.MX SoC or other SoCs from
NXP.

This patchset add the basic support for BBNSM that found on i.MX93.
