ArmPlatformPkg: Fix Ecc error 8001

This patch fixes the following Ecc reported error:
File header doesn't exist File header comment missing
the ""Copyright""

Even though a copyright is present in the header file,
the leading '*' char prevents the Ecc tool from detecting it.
According to the edk2 coding specifcation, section 5.2.3
"File Heading", there should not be leading '*' char.
