as3525: reorder vectored interrupts
The list is ordered by priority, put the DMA and SD interrupts at the top This seems to fix the random freezes on heavy storage operation like building database or pictureflow cache The recently added audio interrupt had a priority higher than SD slot on as3525v1, give it a lower priority git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26160 a1c6a512-1295-4272-9138-f99709370657
