x86/PCI: VMD: Request userspace control of PCIe hotplug indicators
Add set_dev_domain_options() to set PCI domain-specific options as devices are added. The first usage is to request exclusive userspace control of PCIe hotplug indicators in VMD domains. Devices in a VMD domain use PCIe hotplug Attention and Power Indicators in a non-standard way; tell pciehp to ignore the indicators so userspace can control them via the sysfs "attention" file. To determine whether a bus is within a VMD domain, add a bool to the pci_sysdata structure that the VMD driver sets during initialization.
