This adds an optional wrapper around ata_ac_issue_prot that triggers the LED layer.
I plan to use this by allowing PMU LED control on G5 towers. My test platform
is a PowerMac 7,3 (Dual G5 2.0GHz, June 2004) with a K2 (sata_svw) controller.
Respin of an earlier patch, based on comments by Tejun Heo & Alan Cox.
