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
