[PATCH 2/6] nvmem: core: let stride and word_size default to 1

[srinivas . kandagatla]

From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

If the caller doesn't set stride and/or word_size in struct nvmem_config
then nvmem_register accepts this but we may face strange effects later
due to both values being 0. Therefore use 1 as default for both values.
