libata-acpi: implement ata_acpi_associate()
* Add acpi_handle to ata_host and ata_port. Rename ata_device->obj_handle to ->acpi_handle and move it above such that it doesn't get cleared on reconfiguration. * Replace ACPI node association which ata_acpi_associate() which is called once during host initialization. Unlike the previous implementation, ata_acpi_associate() uses ATA_FLAG_ACPI_SATA to choose between IDE or SATA ACPI hierarchy and uses simple child look up instead of recursive walk to match the nodes. This is way safer and simpler. Please read the following message for more info. http://article.gmane.org/gmane.linux.ide/17554 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
