There are 3 different parent clock from different usbphy,
all of them are fixed 480MHz, it is not able to auto select
by clock core to the 2nd and the 3rd parent.
For different use case for different board, we may need to
select different usbphy clock out as parent manually.
Add the clock ID for it so that we can use in dts.

Use the clock ID for usbphy480m_src so that we can find
this clock node in dts.

Aside from clock ID collisions that Heiko can fixup, this looks good to me.
