A DMA descriptor is previously filled in RAM. An I/O access to the
device (frames TrungNguyen1909#22 to TrungNguyen1909#16) start the DMA engine (frame TrungNguyen1909#13). The
engine fetch the descriptor and execute the request, which itself
accesses the SDHCI I/O registers (frame TrungNguyen1909#1 and #0), triggering a
re-entrancy issue.

Fix by prohibit transactions from the DMA to devices. The DMA engine
is thus restricted to memories.
