arm64: zynqmp: add clock-output-names property in clock nodes

[ Upstream commit 385a59e7 ]

Add clock-output-names property to clock nodes, so that the resulting
clock name do not change when clock node name is changed.
Also, replace underscores with hyphens in the clock node names as per
dt-schema rule.
