MIPS: TXx9: 7segled: add missing put_device call
This is required so that we give up the last reference to the device.
Also, add a new tx_7segled_release function which will be called after the
put_device to ensure that device is kfree'd.
[ralf@linux-mips.org: Reformat to Linux coding style and make
tx_7segled_release static.]
