As demonstrated in libata-dev.git#libahci, I think the best route is to 
move generic code into libahci.  In #libahci you will see

	libahci -> common code
	ahci -> standard PCI driver, req's libahci
	mv-ahci -> Marvell AHCI driver, req's libahci
	acard-ahci -> ACard AHCI driver, req's libahci

and to this we could easily add

	platform-ahci -> platform AHCI driver, req's libahci

WARNING:  #libahci should not be used directly, it is meant for 
illustration purposes only.  It has not been properly updated for 
several recent ahci.c changes upstream, which implies that the 
trivial-and-obvious task of moving generic code from ahci.c to libahci.c 
must be redone.
