[Resend PATCH 2/5] ACPI/Resource: Add address translation support

[tianyu.lan@intel.com]

From: Lan Tianyu <tianyu.lan@intel.com>

According ACPI 5.0 spec Section 19.1.8
"For bridges, translate addresses across the bridge, this is the
offset that must be added to the address on the secondary side
to obtain the address on the primary side. Non-bridge devices
must list 0."

This patch is to add address translation offset to the start/end
of struct resource in the acpi_dev_resource_address_space().
Further more, non-bridge device's translation_offset should 0.
So this change will affect other devices.
