docs: fix simple typo, accesssor -> accessor

There is a small typo in bus/controller.h.
Should read `accessor` rather than `accesssor`.

membus: remove duplicated instance of si
...
Fixes a bug introduced in a4f0d72
. read_pif_rom and read_pif_ram were
replaced with a unified read_pif_rom_and_ram, but the excess si instance
remained in the instance mapping.

Optimize extremely aggressively.
...
Tell GCC to optimize cold functions for size and stash them away in
a separate part of the binary. Put the simulate core, meanwhile, on
the hot path. Also, bump optimization to -O3 as we can now "afford"
to do so.

Forgot to mask the data by the dqm before writing it on the bus.
We should do this before putting the data on the bus to prevent
the extra operation in each consumer.
