staging: remove intel_sst driver
Intel has asked that this driver now be removed from the tree, and I am happy to oblige. Cc: Vinod Koul <vinod.koul@intel.com> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
