This patchset replace CONFIG_PM with CONFIG_PM_SLEEP for all virtio drivers and virtio pci driver. With patch 1/2, two compile warnings are eliminated for virtio pci driver, and patch 2/2 is a clean up for all virtio drivers as suggested by Amit Shah.

[PATCH 1/2] virtio_pci: pm: Use CONFIG_PM_SLEEP instead of CONFIG_PM
The virtio_pci_freeze/restore are defined under CONFIG_PM but is used
by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under
CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but
CONFIG_PM_RUNTIME is, the following warning message appeared:
drivers/virtio/virtio_pci.c:770:12: warning: ?virtio_pci_freeze? defined but not
used [-Wunused-function]
static int virtio_pci_freeze(struct device *dev)
^
drivers/virtio/virtio_pci.c:790:12: warning: ?virtio_pci_restore? defined but
not used [-Wunused-function]
static int virtio_pci_restore(struct device *dev)
^
Fix it by changing CONFIG_PM to CONFIG_PM_SLEEP.

[PATCH 2/2] virtio: pm: use CONFIG_PM_SLEEP instead of CONFIG_PM
The freeze and restore functions defined in virtio drivers are used
for suspend and hibernate, so CONFIG_PM_SLEEP is more appropriate than
CONFIG_PM. This patch replace all CONFIG_PM with CONFIG_PM_SLEEP for
virtio drivers that implement freeze and restore callbacks.
