KVM: arm64: Update the identification range for the FF-A smcs

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.
