Currently we found that usb CTRL_PHY_CLK_VALID bit breaks on P1022 platform, which not contains this bit.
 - P1023/P3041/P5020 etc, have this bit
 - P3060/4080/PSC913x do have this bit, but not mentioned in RM.
 - P1022(perhaps and other) has no this bit
I'm waiting for the response from FSL silicon team to confirm whether there is other platform 
not including this bit or not, so this patch maybe have to be pending until I get confirmation.

Thanks,
Shengzhou
