Subject: [PATCH] ACPI: power: Use KERN_DEBUG when no power resources are found

commit a606dac368eed5696fb38e16b1394f1d049c09e9 adds support to link
devices which have _PRx, if a device does not have _PRx, a warning
message will be printed.

This commit is for ZPODD on Intel's platform, on AMD's platform, there
is no _PRx to support ZPODD, we use _PSx.

So instead of printing a useless warning message on AMD's platform,
changing the print level to DEBUG to suppress this message.
