REG:ACPI _CID unique ID test fail

[Senthilkumar, SnegaaX]

Hi all,

The following FWTS errors are reported due to CID/UID conflicting.

With reference to ACPI spec UID must be unique for all the devices and CID or HID may be same across all the devices.

Since CID or HID may be same for all the devices only  UID is unique then why are we throwing error with respect to CID or HID.
