Some older MSM targets combined the AHB clock (what we call pclk) with the core clk and newer targets split the clocks out. Since we don't want to clutter drivers with ifdefs or add checks for IS_ERR clocks add support for a dummy clock. This simplifies drivers because they can always assume a clock is present and error out if it isn't. On top of this, add dummy clocks for 8960 to ease driver development.
