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.

dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from
the devicetree.
