fix(arm_fpga): halve number of PEs per core

Browse source 
When creating the Arm FPGA platform, we had plenty of memory available,
so assigned a generous four PEs per core for the potential CPU topology.
In reality we barely see implementations with two PEs per core, and
didn't have four at all so far.

With some design changes we now include more data per CPU type, and
since the Arm FPGA build supports many cores (and determines the correct
one at runtime), we run out of memory with certain build options.

Since we don't really need four PEs per core, just halve that number, to
reduce our memory footprint without sacrificing functionality.
