Data cache alignment. If any side of the communication uses cache on
rx-region/tx-region this property must be the biggest value of the
invalidation or the write-back size for both sides of the communication.
If no side of the communication uses data cache this property could be
safely omitted.
For example:
Side A: no data cache
Side B: 32 Bytes write-back size, 16 Bytes invalidation size
dcache-alignment = <32>; for both
