Revert "PCI/TSM: Report active IDE streams"
The proposed ABI failed to account for multiple host bridges with the same
stream name. The fix needs to namespace streams or otherwise link back to
the host bridge, but a change like that is too big for a fix. Given this
ABI never saw a released kernel, delete it for now and bring it back later
with this issue addressed.
