[SCSI] ipr: add support for multiple stages of initialization
This patch adds support for using the new IOA initialization feedback register. It also enables 64 bit support in the ipr_ioafp_identify_hrrq and ipr_mask_and_clear_interrupts routines. Signed-off-by: Wayne Boyer <wayneb@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
