Remove unneeded 'startup-hacks' file

Removed the hacks file because there is no reason
for the UART at this point.  Also no longer
need for the serial-stop.  I did confirm that the
VUART is still functioning with these changes.  I
also modified the top level Makefile to no longer
include the hacks directory.

Resolved openbmc/openbmc#586
