Introduce the bare mimimum base of the msm8916 BL31 port. This is pretty much just a standard platform "skeleton" with CPU/memory initialization and an UART driver. This allows booting into e.g. U-Boot with working UART output. Note that the plat/qti/msm8916 port is completely separate and does not make use of anything in plat/qti/common at the moment. The main reason for that is that plat/qti/common is heavily focused around having a binary "qtiseclib" component, while the MSM8916 port is fully open-source (and therefore somewhat limited to publicly documented functionality). In the future it might be possible to re-use some of the open-source parts in plat/qti/common (e.g. spmi_arb.c or pm_ps_hold.c) but it's not strictly required for the basic functionality supported so far.
