[PATCH v2] dt-bindings: mfd: wlf,arizona: Add spi-max-frequency

[Krzysztof Kozlowski]

The Wolfson Microelectronics Arizona audio can be connected via SPI bus
(e.g. WM5110 on Exynos5433 TM2 board), so allow SPI peripheral
properties.

Changes since v1:
1. Allow all SPI properties, not only max-frequency.
