doc: Suggest to use the latest version 8.3 of GCC
At the time of writting, GCC 8.3-2019.03 is the latest version available
on developer.arm.com.
Switch to bare-metal toolchain (arm-eabi-) for AArch32. This allows to
have a finer control on the use of floating-point and SIMD instructions.

It is possible to build TF-A using Clang or Arm Compiler 6. To do so
``CC`` needs to point to the clang or armclang binary, which will
