USB: host: Remove hard-coded octeon platform information for ehci/ohci

Instead rely on device tree information for ehci and ohci.

This was suggested with
http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1401358203-60225-4-git-send-email-alex.smith%40imgtec.com

  "The device tree will *always* have correct ehci/ohci clock
  configuration, so use it.  This allows us to remove a big chunk of
  platform configuration code from octeon-platform.c."

More or less I rebased that patch on Alan's work to remove ehci-octeon
and ohci-octeon drivers.
