jens f55028c696 - pulled PHY out of sdram_ctrl_top.vhd 
- sdram_ctrl_frontend64_wb.vhd implements J-Bus interface and exports abstract PHY interface
- ctrl_ddr_wb64 wraps sdram_ctrl_frontend64_wb and adds specific PHY. This is now our new top level file

jens 7668dd7814 - fixed delta delay. clk0 is generated and evaluated ddr_phy_virtex4 in simulation step n. 
Entities using clk0_out are evaluated in simulation step n+1, causing data sampling during data change.
