SMMUv3: Abort DMA transactions
For security DMA should be blocked at the SMMU by default
unless explicitly enabled for a device. SMMU is disabled
after reset with all streams bypassing the SMMU, and
abortion of all incoming transactions implements a default
deny policy on reset.
This patch also moves "bl1_platform_setup()" function from
arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and
fvp_ve_bl1_setup.c files.
