Why do you need a new compatible for am437x? Isn't "ti,dwc3" sufficient?

There is change in register offsets for AM437x as comapred to Omap5 and 
dra7x.
The compatible is already added in dwc3-omap.c  This patch just updates 
the Documentation.

I was reviewing am43xx usb clock information recently and found out that
PHY clock is missing here. e.g. usb_phy0_always_on_clk32k and usb_phy1_always_on_clk32k.

Can you please add these clocks?
