arm: dts: arm: versatile-ab: Fix duplicate clock node name

Commit 04f08ef ("arm/arm64: dts: arm: Use generic clock and
regulator nodenames") renamed nodes and created 2 "clock-24000000" nodes
(at different paths).

The kernel can't handle these duplicate names even though they are at
different paths.  Fix this by renaming one of the nodes to "clock-pclk".

This name is aligned with other Arm boards (those didn't have a known
frequency to use in the node name).

Fixes: 04f08ef ("arm/arm64: dts: arm: Use generic clock and regulator nodenames")
