Hi Tom,

This PR includes the following changes for v2020.04:

- Various minor fixes for x86
- Switch to ACPI mode on Intel edison
- Support run-time configuration for NS16550 driver
- Update coreboot and slimbootloader serial drivers to use NS16550
run-time configuration
- ICH SPI driver fixes to hardware sequencing erase case
- Move ITSS from Apollo Lake to a more generic location
- Intel GPIO driver bug fixes
- Move to vs2017-win2016 platform build host for Azure pipelines

Azure pipelines result:
https://dev.azure.com/bmeng/GitHub/_build/results?buildId=154&view=results

It just took 1h 57m 0s for Azure to complete the build, but GitLab's
pipelines is still pending. I don't know why.

The following changes since commit 31a790bee939e227dfc7e6a6a323b2b13180707f:
