svn commit: r213345 - head/sys/mips/cavium

[Juli Mallett]

Author: jmallett

New Revision: 213345
URL: http://svn.freebsd.org/changeset/base/213345

Log:
  Rather than shifting offsets by three, set register offset to 3.  All our
  bus interface does that's special here now is to use a 64-bit register size.
  In theory, uart(4) ought to support a regsz as well as regshft and support
  64-bit registers directly.
  
  Also use the UART class's range rather than a hand-coded 1024 for the address
  range.
