Rename non -SP microarchitectures into -SP microarchitectures

This merge request is related to the following error:

✔ ~/g5k/repositories/reference-repository [master|✔] 
20:57 $ rake gen:wiki NAME=hardware SITE=global DO=diff
ERROR while processing spirou-1: ERROR: microarchitecture not found: 'Ice Lake'. Add in hardware.rb
rake aborted!
ERROR: microarchitecture not found: 'Ice Lake'. Add in hardware.rb

Ice Lake architecture should not be referenced in the reference repository since Servers only contains Ice Lake-SP architecture. This merge request change the microarchitecture declared for spirou cluster to Ice Lake-SP so that the rake task will complete succesfully.

This merge request also change microarchitectures for abacus4 and roazhon9 to Skylake-SP, for the same reason.

Finally, to avoid inserting Ice Lake and Skylake microarchitecture (without the -SP part), theses microarchitectures are removed from the microarch lists.
