[RFC PATCH 3/3] security: integrity: call load_uefi_certs() at late_initcall_sync

[Yeoreum Yun <yeoreum.yun@arm.com>]

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.
