Subject: [PATCH] drivers:staging: delete ti-st from staging

From: Pavan Savoy <[email protected]>

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.

Signed-off-by: Pavan Savoy <[email protected]>
