[PATCH 1/2] tee: optee: don't fail on services enumeration failure

[Etienne Carriere]

Change optee probe function to only warn when service enumeration
sequence fails instead of reporting an optee driver probe failure.
Indeed U-Boot can still use OP-TEE even if some OP-TEE services are
not discovered.
