Subject: ahci: request all PCI BARs
From: Tejun Heo <htejun@xxxxxxxxx>
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.
