x86/PCI: Allow x86 platforms to use translation offsets
The memory range descriptors in the _CRS control method contain an address
translation offset for host bridges. This value is used to translate
addresses across the bridge. The support to use _TRA values is present for
other architectures but not for X86 platforms.
For existing X86 platforms the _TRA value is zero. Non-zero _TRA values
are expected on future X86 platforms. This change will register that value
with the resource.
