69f3df4140 Continued work to create clean design:
-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:-)

5bd5d1ff54 Man that's a lot of yak shaving....
-added register read/write properly
-removed redundant wrapper layers in maxi/saxi
-changed over to "emesh" interface from packet 103 bit data
-cleaned up maxi
-cleaned up saxi
-removed redundant signals in elink interface (user,lock,..)
-added wrapper to fifo (to carry emesh interface through)

Now comes the fun part of testing

d45439b43e Changing emesh/elink transaction order
Our "standard packet" order should be followed everywhere to ease verification and integration (standards are good fir reuse...):
[0]=access
[1]=write
[3:2]=datamode
[7:4]=ctrlmode
[39:8]=dstaddr
[71:40]=data
[103:72]=upper-data (or srcaddr)
