Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.
