Optimize rk3399 clocktree by removing CLK_IGNORE_UNUSED of some clocks.

clocks will managered by usb:
- clk_usbphy0_480m_src
- clk_usbphy1_480m_src
- clk_usbphy_480m

clocks will be managered by pvtm:
- clk_pvtm_core_l
- clk_pvtm_core_b
- clk_pvtm_ddr

clocks will be managered by dfi:
- pclk_ddr_mon
- clk_dfimon0_timer
- clk_dfimon1_timer
- aclk_dcf
- pclk_dcf

I gave this a test on a rk3399-gru device and was still able to boot 
sucessfully. So I've applied the patch to my clk-branch for 4.10

Thanks
