ULPI-UTMI translator doesn't work when ULPI drives USB domain

Some time ago reset circuitry was added to the ULPI-UTMI translator for driving the reset pin:

It turns out that this causes a chicken-and-egg problem when the ULPI is clocking the USB domain, as it needs a handful clock cycles for deasserting reset on the ULPI PHY, which won't happen on most ULPI chips when under reset.
