clk: rockchip: rk3399: Add SCLK_USB3OTGx_REF support

Browse Source 
The SCLK_USB3OTGx_REF clocks is used as reference clock for USB3 block.

Add simple support to get rate of SCLK_USB3OTGx_REF clocks to fix
reference clock period configuration.

Also replace use of 24000000 with the OSC_HZ constant.
