When building a kernel with CONFIG_PM=y but neither suspend nor
hibernate support, the compiler complains about the static functions
ath5k_pci_suspend() and ath5k_pci_resume() not being used:

drivers/net/wireless/ath/ath5k/base.c:713:12: warning: ‘ath5k_pci_suspend’ defined but not used
drivers/net/wireless/ath/ath5k/base.c:722:12: warning: ‘ath5k_pci_resume’ defined but not used

Depending on CONFIG_PM_SLEEP rather than CONFIG_PM fixes the issue.
