MIPS: TXx9: 7segled: add missing put_device call

Browse Source 
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.]
