MIPS: IP22: Add missing put_device call

This is required so that we give up the last reference to the device.

Also, create a gio_bus_release() that calls kfree on the device argument to
properly kfree() the memory allocated for the device.

[ralf@linux-mips.org: Reformat to Linux coding style and make
gio_bus_release static.]
