kernel: nvmem: correctly assign fwnode to MMC block device

Use device_set_node to make sure OF node gets assigned on block
devices to be used as NVMEM providers. While block partitions were
already working fine as NVMEM providers, bare block devices such as
mmcblk0boot1 will not work without this change.

Fixes: fc153aa8d9 ("kernel: import pending patches adding support for NVMEM on UBI and MMC")
