The #ifdef checks are hard to get right, in this case some functions
should have been left inside a CONFIG_PM_SLEEP check as seen by this
message:

drivers/net/wireless/ath/wil6210/pcie_bus.c:489:12: error: 'wil6210_pm_resume' defined but not used [-Werror=unused-function]
drivers/net/wireless/ath/wil6210/pcie_bus.c:484:12: error: 'wil6210_pm_suspend' defined but not used [-Werror=unused-function]

Using an __maybe_unused is easier here, so I'm replacing all the
other #ifdef in this file as well for consistency.

A note to myself (unfortunately patchwork doesn't have any way to add
notes to patches): 94162666cd51 is in wireless-drivers-next so this
patch should also go to -next.
