From: Alexander Antonov <alexander.antonov@linux.intel.com>
[ Upstream commit bdc0feee05174418dec1fa68de2af19e1750b99f ]
According to the latest uncore document, DATA_REQ_OF_CPU (0x83), DATA_REQ_BY_CPU (0xc0) and COMP_BUF_OCCUPANCY (0xd5) events have constraints. Add uncore IIO constraints for Snowridge.
