[dv/common] Minor improvement for common drivers
1. tl_host_driver, the logic here is a little bit inefficient:
```
forever begin
seq_item_port.try_next_item(req);
if (req != null) begin
send_a_channel_request(req);
end else begin
// avoid zero delay loop and always align with clock edge to send item
if (reset_asserted) #1ns;
`DV_SPINWAIT_EXIT(@(cfg.vif.host_cb);,
wait(reset_asserted);)
end
end
```
If under reset, then the else statement basically checks every 1ns until
reset_deasserted. It would be much more efficient if just replace the if
statement with a wait reset done. (Thanks @weicai for the suggestion)
2. alert_receiver_base_seq:
Current alert_receiver driver does not support sig_int_error. So I added
a temp constraint here in base sequence.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
