feat(msm8916): add port for MDM9607

The Qualcomm X5 Modem (MDM9607) SoC is very similar to the existing
MSM8916, except for:

  - Single core ARM Cortex-A7
  - No GPU
  - MMU-500 r2p4 instead of r0p0 (need to clear CACHE_LOCK bit)
  - Different default BL31/BL33 address and UART number

Make the existing MSM8916 platform port usable for MDM9607 as well by
adding some minimal if statements where necessary plus the platform
make files for mdm9607.
