To support runtime PM, use the function 'pci_set_power_state' to change
the power state. Therefore, method _PS0 or _PR0 needs to be filled by
platform. So check whether the method is supported, if not, print a
prompt information.

Dave Jones reported the following

	This made it into 5.13 final, and completely breaks NFSD for me
	(Serving tcp v3 mounts).  Existing mounts on clients hang, as do
	new mounts from new clients.  Rebooting the server back to rc7
	everything recovers.

The commit b3b64ebd ("mm/page_alloc: do bulk array bounds check after
checking populated elements") returns the wrong value if the array is
already populated which is interpreted as an allocation failure.  Dave
reported this fixes his problem and it also passed a test running dbench
over NFS.
