prontoespresso/fetch: add verilator lint_off WIDTH around parameters
true_dpram_sclk: explicitly describe read-new-data on read-during-write

Some devices can not infer 'read old data' as memory blocks
(e.g. Cyclone V), so explicitly describe read new data to allow
inferance of memory blocks on such devices.

This change of behaviour should have no impact on the current users
of this module (IMMU), since writes are only performed on one of
the ports by spr accesses, and spr accesses never read and write
at the same time.
