[RFC PATCH 00/14] AHCI power management cleanup

Several AHCI drivers expose suspend/resume functions in a way that can
be simplified. Using pre-processor operation can lead to errors, while
relying on automatic kernel configuration is safer. It also shrinks the
kernel size when CONFIG_PM_SLEEP is not used[1].

This has been compile-tested on x86, arm and arm64.
