This is similar to commit f3e690b00b86 ("clk: mediatek: mt8195:
Implement error handling in probe functions").
Until now the mediatek clk driver library did not have any way to
unregister clks, and so all drivers did not do proper cleanup in
their error paths.
Now that the library does have APIs to unregister clks, use them
in the error path of the probe functions for the mt8192 clk drivers
to do proper cleanup.
