While refactoring the PCI hotplug core's API, I noticed a significant amount of technical debt in some of the hotplug drivers. Document the issues that caught my eye for starters. I do not have hardware at my disposal that utilizes the listed drivers and I think that's a prerequisite to work on them to ensure that no regressions sneak in. But some of this hardware is so old that it may be hard to come by. Obviously, it is fine to support old hardware, but the drivers need to be maintained. If noone steps up, perhaps we should consider sunsetting a few drivers by moving them to staging. Based on my findings, ibmphp would be the first candidate. I've found it fairly difficult to apply my API refactorings to it and have listed some obvious bugs in the driver. cpqphp is also in need of a modernization and would be a second candidate for relegation to staging. shpchp was introduced in the same commit as pciehp but hasn't benefited from the same amount of refactoring due to the decline of conventional PCI's relevance. Yet hardware supporting it may be more prevalent than for the proprietary hotplug methods. Per Documentation/process/2.Process.rst, "a TODO file should be present" for drivers in staging. The file introduced by the present commit may serve as a basis for this.
