[PATCH v2 0/2] Enable ATS for the devices in SATC table

[Yian Chen <yian.chen@intel.com>]

The devices in BIOS SATC (SoC integrated Address Translation Cache)
table are all trusted devices to use ATS. This patch set enables
ATS for them.

---
v2:
  - Use dmar_find_matched_satc_unit() to avoid hard coded
    return value.
  - add static declaration for dmar_ats_supported()
    (the function modified from 
     dmar_find_matched_atsr_unit())
