The FF-A spec 1.2 reserves the following ranges for identifying FF-A calls: 0x84000060-0x840000FF: FF-A 32-bit calls 0xC4000060-0xC40000FF: FF-A 64-bit calls. Use the range identification according to the spec and allow calls that are currently out of the range(eg. FFA_MSG_SEND_DIRECT_REQ2) to be identified correctly.
