The TPL (Targeted Peripheral List) is used for targeted hosts
(non-PC hosts), and it can be used at USB OTG & EH certification
and some specific products which need white list.

commit 052a11d1 (usb: phy: make PHY driver selection
possible by controller drivers) changed the rules
on how drivers/usb/phy/of.c would be compiled and
failed to update include/linux/usb/of.h accordingly.

Because of that, we can fall into situations where
of_usb_get_phy_mode() is redefined. In order to fix
the error, we update the IS_ENABLED() check in
include/linux/usb/of.h to reflect the condition
where of.c is built.

this helper will be used for controllers which
want to work at a lower speed even though they
support higher USB transfer rates.

One such case is Texas Instruments' AM437x
SoC where it uses a USB3 controller without
a USB3 PHY, rendering the controller USB2-only.

This adds two little devicetree helper functions for determining the
dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from
the devicetree.
