usb: kbd: destroy device after console is stopped
In case of IOMUX enabled it assumes that console devices in the list
are available to get them stopped properly via ->stop() callback.
However, the USB keyboard driver violates this assumption and tries
to play tricks so the device get destroyed while being listed as
an active console.
Swap the order of device deregistration and IOMUX update along with
converting to use iomux_replace_device() jelper to avoid the use-after-free.
