This is mainly for the kexec_file_load, make kexec_file_load be able to verify the kernel image agains keys provided by platform or firmware. kexec_file_load already could verify the image agains secondary_trusted_keys if secondary_trusted_keys exits, so this will make kexec_file_load be ware of platform keys as well. This may also useful for things like module sign verify that are using secondary_trusted_keys. I'm not sure if it will be better to move the INTEGRITY_PLATFORM_KEYRING to certs/ and let integrity subsystem use the keyring there, so just linked the .platform keyring into kernel's .secondary_trusted_keys keyring. It workd for my case, tested in a VM, I signed the kernel image locally with pesign and imported the cert to EFI's MokList variable.
