This is the first patch of a serie that show how makefile for specific
platform support may use common rules. comon.mk is introduced. It contains:
- common variable definitions, such as the compilers
- common git to use and path (typically the OP-TEE ones)
- common macros (CCACHE, and others to come).

This is the first commit containing helper makefiles to be able to build
OP-TEE easily regardless of previous knowledge of OP-TEE.

To use this particular git and the makefiles, you should have installed
the environment according to the instructions at:
  https://github.com/OP-TEE/manifest/blob/master/README.md



In this commit there are support for building OP-TEE for:
 - QEMU (default)
 - FVP
 - Hikey

More targets will be added later on.
