[PATCH v4 06/10] nvmem: remove unneeded __nvmem_device_put()

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

__nvmem_device_put() is wrapped by nvmem_device_put() but there's no
extra functionality offered by the latter so just fold one into the
other. There's still the corresponding __nvmem_device_get() so in order
to keep things symmetrical: rename it to nvmem_device_match() to better
reflect its functionality and not confuse users by its presence in the
absence of the similarly prefixed put() counterpart.
