There are some clk_enable() callback add to rockchip clock drivers but with out any real operation driver code, it's waste of CPU cycles at runtime and waste of code size. The callback are add because some peripheral REQUIRE it, eg. ehci/ohci generic driver, and other driver also need it if the ops exist, eg. dwc3 driver and designware net driver.
After update ehci&ohci driver to not always need clk_enable ops in vendor driver, we can remove all relate no use code in rockchip clock drivers.
