Subject: [PATCH v2 02/12] dt-bindings: serial: 8250: correct Nuvoton NPCM850 compatible

Nuvoton NPCM850 UART is compatible with NPCM750, so add proper fallback
to match existing DTS and Linux driver.

Fixes: c8177f90b7c6 ("dt-bindings: serial: 8250: Add npcm845 compatible string")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
