fpga: Update DRAM IO signatures

This updates the IO signatures so that all devices and RFNoC blocks use
the same IO signature for the DRAM. This is needed because the IO
signatures must match between the RFNoC blocks and the devices. This
means that some devices have extra bits in the IO signature for the
address, but the extra bits will simply be ignored.
