Subject: [RESEND PATCH 2/6] perf/x86/intel/uncore: Add uncore support for Snow Ridge server

From: Kan Liang <kan.liang@...ux.intel.com>

The uncore subsystem on Snow Ridge is similar as previous SKX server.
The uncore units on Snow Ridge include Ubox, Chabox, IIO, IRP, M2PCIE,
PCU, M2M, PCIE3 and IMC.
- The config register encoding and pci device IDs are changed.
- For CHA, the umask_ext and filter_tid fields are changed.
- For IIO, the ch_mask and fc_mask fields are changed.
- For M2M, the mask_ext field is changed.
- Add new PCIe3 unit for PCIe3 root port which provides the interface
  between PCIe devices, plugged into the PCIe port, and the components
  (in M2IOSF).
- IMC can only be accessed via MMIO on Snow Ridge now. Current common
  code doesn't support it yet. IMC will be supported in following
  patches.
- There are 9 free running counters for IIO CLOCKS and bandwidth In.
- Full uncore event list is not published yet. Event constrain is not
  included in this patch. It will be added later separately.
