[v2,1/5] nvmem: core: Remove unused devm_nvmem_unregister()

There are no users and seems no will come of the devm_nvmem_unregister().
Remove the function and remove the unused devm_nvmem_match() along with it.

Applied 1/5, 2/5 and 3/5 patches.

Others can go via there own subsystems as I do not see any dependencies.

Thanks!

They are dependent on the patch 3 ("nvmem: core: Check input parameter for
NULL in nvmem_unregister()"). Since there are tags, can you apply them as
