build-scripts: add -a parameter for removing pci & smmu nodesarmlt-20180509-00118.04
This patch adds new build flag -a to build scripts which is used
only when building for FVP_Base_AEMv8A-ARMv8A model. Since this
model doesn't has PCI & SMMU IPs (whereas the device tree has),
user lands in kernel panic while booting Linux in this model.
By passing -a true while building, the PCI & SMMU nodes are
removed in device-tree by which kernel panic is avoided.
