commit af010a02e3eb5f6041cf1dd74f11eacbced07ba0

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
