svn commit: r235698 - head/sys/arm/at91

[Warner Losh]

Author: imp
Date: Sun May 20 20:50:40 2012
New Revision: 235698
URL: http://svn.freebsd.org/changeset/base/235698

Log:
  Minor cleanup before some more major changes:
  o main_clock_hz isn't used, eliminate it
  o move main clock calculation code and table so we have only one ifdef.
