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.
