cover nvmem: fixes for 6.17

From: Srinivas Kandagatla <[email protected]>

Hi Greg,

Here is one nvmem fix which can go for 6.17 release
If its not too late, could you please queue these as 6.17 material.

Fix is mainly to do with module loading of layouts.

Thanks,
Srini

From: Michael Walle <[email protected]>

To support loading of a layout module automatically the MODALIAS variable in the uevent is needed. Add it.
