From: Anson Huang <Anson.Huang@xxxxxxx>
This patch adds an optional property "clock-frequency" to pass
the system counter frequency value to kernel system counter
driver and indicate the driver to skip of_clk operations, this
is to support those platforms using platform driver model for
clock driver.
