[PATCH v5 0/3] 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.

Patch 2 drops redundant clock-names from those single-clock FIU
controllers.

Patch 3 renames the schema to nuvoton,npcm750-fiu.yaml, explains why the
direct-mapped flash window is optional, keeps the requested example
ordering, and simplifies reg/reg-names to the ordered minItems form.

Changes since version 4:
 - Rework patch 2 commit message to describe the DT binding rationale for
   dropping the undocumented FIU clock-names properties.
 - Keep the patch contents unchanged from version 4.

Changes since version 3:
 - Split the DTS cleanup so the reg-names fix stands alone as patch 1.
 - Added review tag to Drop bogus FIU memory reg-names commit.

Changes since version 2:
 - Drop redundant FIU clock-names from the NPCM7xx DTSI together with the
   bogus reg-names cleanup.
 - Rename the schema to nuvoton,npcm750-fiu.yaml and keep reg/reg-names
   immediately after compatible in the example.
 - Explain why the direct-mapped flash window is optional and model
   reg/reg-names as ordered minItems arrays.
 - Drop clock-names from the schema to match the driver and updated DTS.

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