Ah, yes, I missed that.  But register access only needs ipg clock and
per clock still does not need to be enabled here, right?

Look, here is what you do in .probe().

	clk_prepare_enable(sport->clk_per);
	clk_prepare_enable(sport->clk_ipg); 
	...
	uart_add_one_port(&imx_reg, &sport->port);
	...
	clk_disable_unprepare(sport->clk_per);
	clk_disable_unprepare(sport->clk_ipg);

Since imx_console_setup() will be called in uart_add_one_port() and
clocks are already being taken care of in imx_console_setup(), why do
you need all these clock operations here at all?
