Subject: [PATCH 8/9] [SCSI] aacraid: Send commit-config to controller firmware

From: Rajinikanth Pandurangan <rajinikanth.pandurangan@pmcs.com>

Description:
	Controller BIOS/UEFI driver used to send this request.  But for
	IBM-Power system there is no BIOS/UEFI driver.  So this change is
	required for IBM, otherwise controller will be read-only mode.
