[PATCH v10 6/6] KVM: arm64: Bump the supported version of FF-A to 1.2

[Per Larsen via B4 Relay]

From: Per Larsen <perlarsen@xxxxxxxxxx>

FF-A version 1.2 introduces the DIRECT_REQ2 ABI. Bump the FF-A version
preferred by the hypervisor to enable implementation of the 1.2-only
FFA_MSG_SEND_DIRECT_REQ2 and FFA_MSG_SEND_RESP2 messaging interfaces.
