This patch adds support for the PCIe SSD Status LED Management
interface, as described in the "_DSM Additions for PCIe SSD Status LED
Management" ECN to the PCI Firmware Specification revision 3.2.
It will add a single (led_classdev) LED for any PCIe device that has the
relevant _DSM. The ten possible status states are exposed using
attributes current_states and supported_states. Reading current_states
(and supported_states) will show the definition and value of each bit:

Any comments? I think I sent at a bad time originally. Thanks!
