Benjamin Herrenschmidt c19b5b8cc7 litedram: Update to new LiteX/LiteDRAM version 
Things have changed a bit in upstream LiteX. LiteDRAM now exposes a
wishbone for the CSRs for example.

Benjamin Herrenschmidt 025cf5efe8 syscon: Add syscon registers 
These provides some info about the SoC (though it's still somewhat
incomplete and needs more work, see comments).

There's also a control register for selecting DRAM vs. BRAM at 0
(and for soft-resetting the SoC but that isn't wired up yet).

Benjamin Herrenschmidt 3ac815823c fpga: Hookup Arty to litedram

Arty has its own top-arty.vhdl which supports litedram and is now
hooked up
