dt-bindings: nvmem: brcm,nvram: add #nvmem-cell-cells for MACs
...
Broadcom's NVRAM contains MACs for Ethernet interfaces. Those MACs are
usually base addresses that are also used for calculating other MACs.
For example if a router vendor decided to use gmac0 it most likely
programmed NVRAM of each unit with a proper "et0macaddr" value. That is
a base.
Ethernet interface is usually connected to switch port. Switch usually
includes few LAN ports and a WAN port. MAC of WAN port gets calculated
as relative address to the interface one. Offset varies depending on
device model.
Wireless MACs may also need to be calculated using relevant offsets.
To support all those scenarios let MAC NVMEM cells be referenced with an
index specifying MAC offset. Disallow additionalProperties while at it.

dt-bindings: nvmem: Drop unneeded quotes
...
Cleanup bindings dropping unneeded quotes. Once all these are fixed,
checking for this can be enabled in yamllint.

dt-bindings: nvmem: brcm,nvram: add basic NVMEM cells
...
NVRAM doesn't have cells at hardcoded addresses. They are stored in
internal struct (custom & dynamic format). It's still important to
define relevant cells in DT so NVMEM consumers can reference them.
Update binding to allow including basic cells as NVMEM device subnodes.

dt-bindings: nvmem: Add missing 'reg' property
...
With 'unevaluatedProperties' support implemented, the following warnings
are generated in the nvmem examples:
Documentation/devicetree/bindings/nvmem/st,stm32-romem.example.dt.yaml: efuse@1fff7800: Unevaluated properties are not allowed ('reg' was unexpected)
Documentation/devicetree/bindings/nvmem/rmem.example.dt.yaml: nvram@10000000: Unevaluated properties are not allowed ('reg' was unexpected)
Documentation/devicetree/bindings/nvmem/brcm,nvram.example.dt.yaml: nvram@1eff0000: Unevaluated properties are not allowed ('reg' was unexpected)
Add the missing 'reg' property definition.
