[CAUTION: External Email]

(Resending patch with [edk2-platforms] prefix with correct emailid).
GCC compiler puts the DevicePath PCDs to the read-only section. During boot if try to process the device path after PtrGetPtr it throws a page fault exception.

Hence making a local copy using DuplicateDevicePath() to avoid the page fault exception.
