feat(msm8916): add port for MSM8909

Browse source 
The Qualcomm Snapdragon 210 (MSM8909) SoC is very similar to the
existing MSM8916, except for:

  - ARM Cortex-A7 instead of Cortex-A53 (AArch32-only)
  - MMU-500 r2p0 instead of r0p0 (need to clear CACHE_LOCK bit)
  - Different default BL31 address and UART number

Make the existing MSM8916 platform port usable for MSM8909 as well by
adding some minimal if statements where necessary plus the platform
make files for msm8909.
