SAM3U: Use correct DMAC peripheral ID for SSC receive
It seems like the SSC Rx channel has a different DMAC peripheral ID (4)
than the transmit side.
The official Atmel sam3u documentation (doc6403e) doesn't document that
fact, and it also doesn't even state any DMAC peripheral identifiers.
The at91lib code release by Atmel claims it is 3, when in reality it is
4!
I found this by brute-forcing all possible peripheral identifiers.
