fsldma: Set correct dma_mask based on hw capability
The driver currently hardcodes DMA_BIT_MASK to 36-bits, which is only
correct on eloplus:
elo3 supports 40-bits
eloplus supports 36-bits
elo supports 32-bits
This is based on 0x08 cdar register documention in the respective
reference manuals. Set the dma mask accordingly.
Feedback from Arnd Bergmann:
- Use match data to set address bit mask
