[PATCH RFC v4 02/10] libahci: Move ahci_host_priv declaration to include/linux/ahci.h

[Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

With the ahci-platform.c changes later in this patch-set, some
arch/arm/mach-foo/*.c sata drivers need access to ahci_host_priv, so move
its declaration outside of drivers/ata.
