[PATCH v3 5/5] clocksource: armada-370-xp: Add detailed clock requirements in devicetree binding

[Ezequiel Garcia]

Specifies the required clock inputs for each supported compatible.
Armada 370 requires a single clock phandle, and Armada XP requires
two clock phandles with clock-names "nbclk" and "fixed".
