[PATCH v2 0/2] Nuvoton NPCM FIU DTS fixes and binding conversion

This series fixes the in-tree NPCM7xx FIU controller nodes so their
resources match what the DTS actually describes, and converts the legacy
Nuvoton NPCM FIU binding to YAML DT schema.

Patch 1 drops the bogus "memory" entry from reg-names on the NPCM7xx FIU
nodes, which only describe the control register window today.

Patch 2 replaces the TXT binding with a YAML schema, documents the optional
memory-mapped flash window explicitly, and accepts the existing FIU
clock-names used by the in-tree DTS users.

Addressed comments from:
 - Krzysztof Kozlowski : https://lkml.org/lkml/2025/11/13/473

Changes since version 1:
 - Drop interrupts property.
 - Drop unused label.
 - Keep reg as the second property, followed by reg-names.
