ACPICA: Add starting offset parameter to common dump buffer routine
Rename the dump buffer routines. Offset parameter can specify the buffer starting offset that is used when displaying each line of the buffer. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
