[PATCH v6.8 2/2] nvmem: drop nvmem_layout_get_match_data()

From: Rafał Miłecki <rafal at milecki.pl>

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().
