ia64: remove the SGI UV simulator support
The simulator support was marked as temporary since the initial commit, so drop it more than 10 years later. Signed-off-by: Christoph Hellwig <hch@lst.de> Link: https://lkml.kernel.org/r/20190813072514.23299-22-hch@lst.de Signed-off-by: Tony Luck <tony.luck@intel.com>
