Only the clocks initialized by the new entries you added are marked disabled (or rather, not actively enabled; if they're enabled already, they won't be disabled). We should treat all UARTs equally. Historically we've needed to enable the serial clocks forcibly since the regular serial driver didn't call clk_get() or clk_prepare_enable() on any clocks, but I notice that it does now, since sometime in kernel 3.8. As such, I think you can modify all the UART entries in these tables to have the enable/state field set to false (0). Can you try that and check that it works for the serial console ports?
