UBUNTU: SAUCE: LIBIO: Support the dynamically logical PIO registration of ACPI host I/O
BugLink: http://bugs.launchpad.net/bugs/1677319
For those hosts which access I/O based on the host/bus local I/O addresses,
their I/O range must be registered and translated as unique logical PIO before
the ACPI enumeration on the devices under the hosts. Otherwise, there is no
available I/O resources allocated for those devices.
This patch implements the interfaces in LIBIO to perform the host local I/O
translation and set the logical IO mapped as ACPI I/O resources.
