Binding for fixed NVMEM cells defined directly as NVMEM device subnodes

New syntax is meant to be clearer and should help avoiding imprecise
bindings.

NVMEM subsystem already supports the new binding. It should be a good
idea to limit support for old syntax to existing drivers that actually
support & use it (we can't break backward compatibility!). That way we
additionally encourage new bindings & drivers to ignore deprecated
binding.

It wasn't clear (to me) if rtc and w1 code actually uses old syntax
fixed cells. I enabled them to don't risk any breakage.

is there any chance I can have this accepted / pushed, please?

It's a tiny optimization and it makes sure people don't use deprecated
syntax with new drivers.

I also noticed this will probably let me drop an unclear and
non-intuitive no_of_node config option.
