ftgmac100: Disable HW checksum generation on AST2400, enable on others
We found out that HW checksum generation only works from AST2500 onward. This disables it on AST2400 and removes the "no-hw-checksum" properties in the device-trees. The problem we had wasn't related to NC-SI. Also rework the logic testing for that property so it can be used to disable HW checksum generation and checking regardless of whether NC-SI is used or not in case other variants out there need this.
