    intel: Correct MMIO related ACPI table settings
    
    Several of the intel platforms define the region reserved
    for PCI memory resources in a location where it overlaps
    with the MMIO (MCFG) region.
    
    Using the memory map from mohon_peak as an example:
    
      0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES
      1. 0000000000001000-000000000009ffff: RAM
      2. 00000000000a0000-00000000000fffff: RESERVED
      3. 0000000000100000-000000007fbcffff: RAM
      4. 000000007fbd0000-000000007fbfffff: CONFIGURATION TABLES
      5. 000000007fc00000-000000007fdfffff: RESERVED
      6. 00000000e0000000-00000000efffffff: RESERVED
      7. 00000000fee00000-00000000fee00fff: RESERVED
      8. 0000000100000000-000000017fffffff: RAM
    
      The ACPI table describing the space set aside for PCI memory
      (not to be confused with the MMIO config space) is defined
      as the region from BMBOUND (the top of DRAM below 4GB) to
      a hardcoded value of 0xfebfffff. That region would overlap
      the MMIO region at 0xe0000000-0xefffffff. For rangeley
      the upper bound of the PCI memory space should be set
      to 0xe0000000 - 1.
    
      The MCFG regions for several of the affected chipsets are:
      rangeley    0xe0000000-0xefffffff
      baytrail    0xe0000000-0xefffffff
      haswell     0xf0000000-0xf3ffffff
      sandybridge 0xf8000000-0xfbffffff
    
    TEST = intel/mohonpeak and intel/bayleybay.
