The partitions.yaml schema is an unusual structure in that it includes
all possible partition types, and it disables the normal matching by
compatible strings. As partitions.yaml has nothing to match on, it is
only applied when explicitly referenced. The use of "oneOf" also results
in misleading warnings which are difficult to understand. Drop
partitions.yaml and rely on the standard compatible matching instead.

The "mmc-card" case previously allowed any partition type, but now only
allows "fixed-partitions". There aren't any users and the original
intent appeared to be only for "fixed-partitions".

It would actually be great to also allow 'gpt-partitions' as compatible
type with #address-cells = <0> and #size-cells = <0> and allow matching
on partition UUID, name or index. This has previously been discussed and
would avoid having to extract MAC addresses and WiFi EEPROM data in
userspace on many devices which rely on such conventions.

Out of curiosity, why not exposing this data through an NVMEM cell
instead? Anyway, this (re?)addition can probably be part of a follow-up
series and is almost orthogonal to this cleanup IMO.
