The ACPI _HRV object on the device is used to supply Linux with the device's hardware revision. This is an optional object. Add sysfs support for the _HRV object if it exists on the device.
This change allows users to easily find the hardware version of non-PCI hardware by looking at the sysfs 'hrv' file. It is most useful for non-PCI devices because lspci can list the hardware version for PCI devices.
