more space.

cpu/software: move CPU specific software from the BIOS to the CPU directories.
...
This simplifies the integration of the CPUs' software, avoid complex switches in the code,
and is a first step to make CPUs fully pluggable.
The CPU name is no longer present in the crt0 files (for example crt0-vexriscv-ctr.o
becomes crt0-ctr.o) so users building firmwares externally will have to update their
Makefiles to remove the $(CPU) from crt0-$(CPU)-ctr.o.

travis: add back test on python3.5 (python3.6 is recommended but we can try to keep 3.5 compatibility until we have good reason to no longer support it).
