[PATCH 1/3] nvmem: core: Remove unused nvmem_device_cell_(read|write)

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

nvmem_device_cell_read() and nvmem_device_cell_write() were
added in 2015's
commit e2a5402ec7c6 ("nvmem: Add nvmem_device based consumer apis.")
but have remained unused.

Remove them.

 Before the consumers can read/write NVMEM directly, it should get hold
 of nvmem_controller from one of the `*nvmem_device_get()` api.
