KVM: arm64: Block unsafe FF-A calls from the host
When KVM is initialised in protected mode, we must take care to filter
certain FFA calls from the host kernel so that the integrity of guest
and hypervisor memory is maintained and is not made available to the
secure world.
As a first step, intercept and block all memory-related FF-A SMC calls
from the host to EL3 and don't advertise any FF-A features. This puts
the framework in place for handling them properly.
