Daniel Henrique Barboza 04eb30a03c target/riscv: add 'vlenb' field in cpu->cfg 
Our usage of 'vlenb' is overwhelming superior than the use of 'vlen'.
We're using 'vlenb' most of the time, having to do 'vlen >> 3' or
'vlen / 8' in every instance.

In hindsight we would be better if the 'vlenb' property  was introduced
instead of 'vlen'. That's not what happened, and now we can't easily get
rid of it due to user scripts all around. What we can do, however, is to
change our internal representation to use 'vlenb'.

Add a 'vlenb' field in cpu->cfg. It'll be set via the existing 'vlen'
property, i.e. setting 'vlen' will also set 'vlenb'.

We'll replace all 'vlen >> 3' code to use 'vlenb' directly. Start with
the single instance we have in target/riscv/cpu.c.
