clk: mediatek: apmixed: Drop error message from clk_register() failure

mtk_clk_register_ref2usb_tx() prints an error message if clk_register()
fails. It doesn't if kzalloc() fails though. The caller would then tack
on its own error message to handle this.

Also, All other clk registration functions in the MediaTek clk library
leave the error message printing to the bulk registration functions,
while the helpers that register individual clks just return error codes.

Drop the error message that is printed when clk_register() fails in
mtk_clk_register_ref2usb_tx() to make its behavior consistent both
across its failure modes, and with the rest of the driver library.
