Some controllers may not have separate memory maps and interrupts

Not really. As long as you have dwc3 core as a separate device, you can
add a node for it.
Just that the glue should create a device for dwc3 core using
of_platform_populate.(You can have a look at
drivers/usb/dwc3/dwc3-omap.c in usb-next)
Moreover, SoCs having multiple dwc3 controllers will have multiple
PHYs, which eventually be added using usb_add_phy_dev(), and not
using usb_add_phy(). So each dwc3 controller won't be able to
get PHYs by simply calling devm_usb_get_phy() also.
No. We have added usb_get_phy_dev() for that purpose in the case of non-dt.
I think, instead you can have a patch to use devm_usb_get_phy_dev() here
and in exynos platform specific code use usb_bind_phy() to bind the phy
and controller till you change it to dt.
In such cases, dwc3 should expect PHYs from its parent's node.
NAK.
Thanks
