HID: do not try to compile PM code with CONFIG_PM unset
Fixes this build breakage in case when CONFIG_PM is not set drivers/hid/usbhid/hid-core.c: In function 'hid_suspend': drivers/hid/usbhid/hid-core.c:1220: error: 'struct usb_device' has no member named 'auto_pm' drivers/hid/usbhid/hid-core.c:1245: error: 'struct usb_device' has no member named 'auto_pm' drivers/hid/usbhid/hid-core.c:1258: error: 'struct usb_device' has no member named 'auto_pm' by throwing both the hid_suspend() and hid_resume() away completely in such case, as they won't be used anyway.
