In the arm64 pKVM environment, all FF-A requests fail until the FF-A driver is initialized, as the FF-A version is not negotiated with the hypervisor beforehand. When FF-A is built-in and pKVM is enabled, pKVM finalises its initialization at the device_initcall_sync level, while the FF-A driver is initialized later at the late_initcall stage via deferred probe. When the EFI variable service runs with StandaloneMm, it uses FFA_DIRECT_MSG to access EFI variables. As a result, load_uefi_certs() always fails in this environment. To address this issue, defer load_uefi_certs() to the late_initcall_sync level.
