staging: delete ti-st from staging 

The 2 drivers originally staged, the core ti-st driver
and the btwilink bluetooth driver have now moved to relevant
directories, so deleting the ti-st/ from staging.

This enables the Bluetooth driver for TI BT/FM/GPS combo devices.
This makes use of shared transport line discipline core driver to
communicate with the BT core of the combo chip.

TODO:
1. Step up and maintain this driver to ensure that it continues
to work. Having the hardware for this is pretty much a
requirement. If this does not happen, the will be removed in
the 2.6.35 kernel release.
Please send patches to Greg Kroah-Hartman <greg@kroah.com>.
