Beautification & Homogeneization

[FrancescoConti]

This purely cosmetic PR:

• makes the internal style used in PULP SOC a bit more consistent
• aligns to the common PULP practice in terms of indentation (2 spaces), which also follows the lowrisc guidelines

Are you using verible-format for these changes?

Are you using verible-format for these changes?

In theory, it should be doable with verible-format with these options:

verible-verilog-format --column_limit 256 --wrap_spaces 2 file.sv

plus probably a few more for the various alignments. In practice I did it by hands, as verible fails to converge with an error (at least on my setup).

I think it is ready. @bluewww ?
