DV cleanup
...
-Set VCO_MULT to 1 for PLL. Dirty hack to allow the RX clk to phase align with the input. Otherwise, if you multiply the VCO clock and then divide, you get a random phase alignment the way the current clock divider is written.
-Changed the fifo_cdc to 32 entries. Forgot that I had changed the fifo_cdc to hard coded per number of entries. Really need to have a parametrixed model that works!!
