Sansa AMS: VIC_INT_ENABLE register is not a mask

Browse source 
When read it returns all enabled interrupt sources
When written it enables interrupt sources for each bit set
So just like VIC_INT_EN_CLEAR, we don't have to read the previous value
before writing to it (VIC_INT_EN_CLEAR is write-only anyway)

Thanks to Fred Bauer for spotting
