libata: convert to iomap
Convert libata core layer and LLDs to use iomap. * managed iomap is used. Pointer to pcim_iomap_table() is cached at host->iomap and used through out LLDs. This basically replaces host->mmio_base. * if possible, pcim_iomap_regions() is used Most iomap operation conversions are taken from Jeff Garzik <jgarzik@pobox.com>'s iomap branch.
