Move generic architectural setup out of blx_plat_arch_setup().
blx_plat_arch_setup() should only perform platform-specific architectural setup, e.g. enabling the MMU. This patch moves generic architectural setup code out of blx_plat_arch_setup(). Change-Id: I4ccf56b8c4a2fa84909817779a2d97a14aaafab6
