Title:
  [Bug]Avoid PCI BAR setup warning on Broadwell-EP boot

Status in intel:
  New
Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Xenial:
  Fix Committed

Bug description:
  BDW-DE/EP/EX has an errata that results in a warning at boot
  [ 1.821602] pci 0000:ff:1e.3: [Firmware Bug]: reg 0x10: invalid BAR (can't size)
  The problem is just the warning, there is no functional issue
  Dell requested to hide the warning. The only way to do that is through a Linux patch. 
  errata:
  98 b308166 - BAR1 to BAR5 in HA returns non-zero values after writing
  0xFFFFFFFF to it.
  Problem: During BAR initialization the Operating System will try to access BAR registers. Bar1 to
  Bar 5 HA (Dev 0x12, Func 0 , 4 Reg 0x14 - 0x24) returns non-zero values after writing
  0xFFFFFFFF to it.
