[PATCH] libata: Convert LED disk trigger from IDE to libata

This patch converts the trigger for the LED at the front of Apple's
iBooks to libata. It's merely a replacement of the string ide by disk.

The patch is taken from http://dev.gentoo.org/~josejx/ata.patch. I've
asked Joseph Jezak if he intends to send this patch upstream, but as he
did not reply I'll do so.
