The MT8192 topckgen clock driver is split into two parts, an early
CLK_OF_DECLARE_DRIVER() part which registers one clock solely for the
system timer, and a standard platform driver part that handles the rest.

In both parts, of_clk_hw_add_provider() is called, causing the clk
provider to be added twice. While this doesn't cause issues, it isn't
clean either.

Remove the existing entry before calling of_clk_hw_add_provider() in
the platform driver probe function. This ensures that there is only
one entry, and the OF related code still runs on the full set of
clocks.
