Earlgrey: alert_handler_reg_wrap doesn't work in Verilator after Opentitan update

[rkapuscik]

After updating Opentitan to newest version, alert_handler_reg_wrap test is failing with:

%Error: Could not get lowconn handle for port, aborting
%Error: Internal Error: ../V3Ast.cpp:346: Null item passed to setOp1p

Looks like we're missing some dependencies.

#520 adds missing dependencies.
But there are another errors, which are thrown only when uhdm-verilator is used:
