This is the same changes which ones were done in the linux repo for all
AST2500 based DTS.

Original commit is ed7120aa   Andrew Jeffery <andrew@aj.id.au>
  "ARM: dts: aspeed: Add RCLK to MAC clocks for RMII interfaces"

We need to ungate RCLK on AST2500- and AST2600-based platforms for RMII
to function. RMII interfaces are commonly used for NCSI.
