svn commit: r190771 - head/sys/dev/dcons

New Revision: 190771

Log:
  Reduce the dcons polling frequency to 25 Hz.
  
  It makes little sense to use 100 Hz polling in dcons. We cannot live
  without polling, because that's just how dcons works. It polls the
  buffer filled by the firewire hardware. 25 Hz is probably enough for
  most use cases.
