arm_fpga: Add ROM trampoline

The application cores of the FPGAs used in Arm Ltd. start execution at
address 0x0. This is the location of some (emulated) ROM area (which can
be written to by the uploading tool).
Since the arm_fpga port is configured to run from DRAM, we load BL31 to
the beginning of DRAM (mapped at 2GB). This requires some small
trampoline code in the "ROM" to jump to the BL31 entry point.

To avoid some extra magic binary, add a tiny assembly file with that
trivial jump instruction to the tree, so this binary can be created
alongside BL31.
