dt-bindings: mmc: Document fixed-layout NVMEM provider support

Browse source

Allow an eMMC hardware partition node to describe an NVMEM layout so the
partition can be exposed as an NVMEM provider. This lets a partition
(e.g. an eMMC boot partition) store device-specific information such as a
WiFi MAC address or a Bluetooth BD address and reference it through NVMEM
cells.

Accept "fixed-layout" as the partition node compatible, in addition to
"fixed-partitions", so the layout can be described directly on the
partition node.
