[PATCH v2] dt-bindings: nvmem: st,stm32-romem: align patternProperties regex on nvmem-deprecated-cells.yaml

[Fabrice Gasnier]

The patternProperties key only matched node names of the form
"name at address" ("^.*@[0-9a-f]+$"). It did not match nodes using the
extra unit-address index used to disambiguate cells sharing the same
reg, e.g. "trim-rd-cc1 at 1e8,4", causing dtbs_check failures such as:

efuse at 44000000 (st,stm32mp25-bsec): Unevaluated properties are not
allowed ('trim-rd-cc1 at 1e8,4', ...)

Align the regex with the one used in nvmem-deprecated-cells.yaml
("@[0-9a-f]+(,[0-7])?$") so both patternProperties definitions apply
to the same set of node names.
