From: Anshuman Gupta <anshuman.gupta@intel.com>

Implement _DSM method 0Ah according to PCI firmware specifications,
section 4.6.10 Rev 3.3., to request auxilary power needed for the
device when in D3Cold.

Note that this implementation assumes only a single device below the
Downstream Port will request for Aux Power Limit under a given
Root Port because it does not track and aggregate requests
from all child devices below the Downstream Port as required
by Section 4.6.10 Rev 3.3.

One possible mitigation would be only allowing only first PCIe
Non-Bridge Endpoint Function 0 driver to call_DSM method 0Ah.

What's this S-o-b for?

Varun was handling this patch from Anshuman earlier. Anshuman can you please confirm whether the contribution 
from Varun was significant and needed to be co-developed or can this S-o-b be safely dropped in future versions.

Thanks,
Badal
