2020-04-05clk: socfpga: Read the clock parent's register base in probe functionChee Hong Ang
This commit (82de42fa14682d408da935adfb0f935354c5008f) calls child's ofdata_to_platdata() method before the parent is probed in dm core. This has caused the driver no longer able to get the correct parent clock's register base in the ofdata_to_platdata() method because the parent clocks will only be probed after the child's ofdata_to_platdata(). To resolve this, the clock parent's register base will only be retrieved by the child in probe() method instead of ofdata_to_platdata().

But, unlike Linux U-Boot won't require to handle these vopl assigned-clocks since core clocks are enough to handle the video out to process.
