Shiqing Gao 789899d05f dm: deal with physical GSI sharing
- hardcode the devices' GSI info based on the platform
- reject the passthrough if the following requirement is not met
  all the PCI devices that are sharing the same GSI should be assigned
  to same VM to avoid physical GSI sharing between multiple VMs.

v4 -> v5
 * Move the gsi_dev_mapping_tables definition in a separate file
 * Add the GSI info that might be used by GPIO
 * Update the HW name

v3 - > v4
 * Refine the format of raw data to improve the readability
 * Remove the redundant code when adding the new dev into the gsi
    sharing group

v2 -> v3
 * Add the MSI/MSI-x capability check
   Do not add the device which supports MSI/MSI-x to the GSI sharing
   group.

v1 -> v2
 * Update the GSI raw data based on SBL
 * Free the resources when gsi sharing violation occurs
 * Move the MACRO PCI_BDF(b, d, f) to pci_core.h since passthrough.c
    and gsi_sharing.c are both using it

Geoffroy Van Cutsem da1c860e8c Fix compilation on Ubuntu 14.04
A couple of problems appeared on Ubuntu 14.04 (gcc 4.8.4) when we
turned on additional compiler flags with commit
519c4285cf104a594776591075ee1c6ee4d61815a. This patch fixes these
problems by adhering to the strict anti-aliasing rules and also
initializing the 'tfd' variable where the compile believed it
_could_ be used uninitialized.

Yin Fengwei f0b74016d1 DM: release mmio data structure for pci bar
We didn't release mmio/io data structure related with PCI bar
of pci dev. Which could trigger memory leak when reboot UOS.

With the new patch, we release the mmio/io data structure
when pci core tries to deinit pci device.
