openrisc: io: Define iounmap argument as volatile (2022-07-30 05:50:15 +0900)

OpenRISC fixes for 5.20-rc1/6.0

In this cycle we add PCI support to OpenRISC used in our new QEMU virt platform. The base of this series is a merge of Bjorn's PCI headers cleanup branch and 5.16-rc6. The patches from the PCI branch are needed for the series to work.

The main updates from me include:
- Kconfig updates to support OpenRISC PCI (just config now after the PCI cleanups I did on Bjorn's branch)
- A new defconfig for the qemu virt platform.
- Also there is one MAINTAINERS update. As I was working on the PCI series we kept getting bounces from Richard's old email address. I added this here; I am not sure how these are usually handled when the maintainer doesn't queue it themselves.
