ahci: request all PCI BARs
ahci is often implemented with accompanying SFF compatible interface and legacy IDE driver may attach to the legacy IO ports when the controller is already claimed by ahci and vice-versa. This patch makes ahci use pcim_iomap_regions_request_all() so that all IO regions are claimed on attach. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
