[PATCH 6.4 632/800] nvmem: rmem: Use NVMEM_DEVID_AUTO

From: Phil Elwell <phil@raspberrypi.com>

[ Upstream commit 09dd7b993eddb3b48634fd5ddf27aa799785a9ee ]

It is reasonable to declare multiple nvmem blocks. Unless a unique 'id'
is passed in for each block there may be name clashes.

Avoid this by using the magic token NVMEM_DEVID_AUTO.

Fixes: 5a3fa75a4d9c ("nvmem: Add driver to expose reserved memory as nvmem")
