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=resul...

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:
