While implementing support for this USB controller in U-Boot, I noticed
that the reset line alsp affects they PHY. It looks like most platforms
use a separate glue node to represent this, and in fact there is already
a compatible for the H6 listed in drivers/usb/dwc3/dwc3-of-simple.c.

Since this layout matches the usual way of modeling this hardware, it
allows using the existing drivers without adding platform-specific code.
