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.
