-Adding enable signal to clock out. Definitely right decision to keep
separate bit from the divider field.
-Fixed settings for to fit new register field
-XILINX version is still broken!!
old implementation felt too "cutsy"
this makes for a cleaner usage model (simple shift with param)
also splitting out enable but, not making the CTIMER mistake again
-changed ecfg clock default values, elink default is now the PLL clock/128 coming out of reset
-should work in any implementation?
-still have to implement the Xilinx specific stuff
-pll bypass for clocks (customer request)
-adding dividers on all clocks (tx/cclk)
-adding reset block (clearer)
-using commong clock_divider block
-need to clean up divider block later today, slightly broken:-)
