[PATCH 3/5] arm: socfpga: soc64: Move socfpga_init_smmu() to before boot SSBL

[Jit Loon Lim <jit.loon.lim@intel.com>]

From: Ley Foon Tan <ley.foon.tan@intel.com>

socfpga_init_smmu() change the L3 masters (eg: SDMMC, NAND and etc) to
non-secure , this cause the failure when L3 masters loading SSBL image to
secure region in DDR.

Move socfpga_init_smmu() to spl_perform_fixups(), so, it is called prior
running SSBL.
