Thanks for layouts refactoring we now have "struct device" associated
with layout. Also its OF pointer points directly to the "nvmem-layout"
DT node.

All it takes to get match data is a generic of_device_get_match_data().

Isn't device_get_match_data() preferred?

You're right. I think a big crusade against of_device_get_match_data()
is still ahead of us but I'll make sure to use device_get_match_data()
in U-Boot env layout to shine as an example :)

Thank you for quick reviews!
