The HW model validation that guards the indirect SRAM checking in the
VCN code path is redundant - there's no model that's not included in the
switch, making it useless in practice [0].
So, let's remove this switch statement for good.

V2:
* Changed the approach after ML discussion- instead of cleaning up
the switch statement, removed it entirely - special thanks to Alex
and Mario for the feedback!
Notice that patch 3 was dropped from this series after reviews.
