anlogic: add support for Eagle Distributed RAM
The MSLICEs on the Eagle series of FPGA can be configured as Distributed RAM. Enable to synthesis to DRAM. As the Anlogic software suite doesn't support any 'bx to exist in the initializtion data of DRAM, do not enable the initialization support of the inferred DRAM.
