[0/3] KVM: arm64: Separate the hyp FF-A buffers init from the host

Hello,

This moves the initialization of the hypervisor FF-A buffers
away from the host FF-A map calling path. If the hypervisor
cannot map the buffers with Trustzone, it rejects any FF-A call
when it runs under protected mode. 
Other than that it moves the definitions of the ffa_to_linux_err
map from the arm_ffa driver to the ffa header so that the hyp code
can make use of it.

Thanks,
