allwinner: Add BL32 (corresponds to Trusted OS) support
This patch is an attempt to run Trusted OS (OP-TEE OS being one of them) along
side BL31 image.
ATF supports multiple SPD's that can take dispatcher name (opteed for OP-TEE OS)
as an input using the 'SPD=<dispatcher name>' option during bl31 build.
