arc: emsdp: Add more platform-specific compiler options
Even though EM SDP is FPGA-based board and different FPGA
images (known as .bit-files) are awailable for the board still
there's a common subset of options we may rely on for all configs.
These are:
* Normalizer
* Swap instructions
* Simple multiplier
* Barrel-shifter
* Floating-point unit
* Shorter instructions (code density)
This among other improvements allows to compile code with
64-bit divisions, see [1].
