Requires the usb_hs feature.
ULPI Transciever Delay
Some ULPI PHYs like the Microchip USB334x series require a delay between the
ULPI register write that initiates the HS Chirp and the subsequent transmit
command, otherwise the HS Chirp does not get executed and the deivce
enumerates in FS mode. The STM32H7 series supports adding this delay to work
with the affected PHYs. Enable the synopsys-usb-otg/xcvrdly feature to add
this delay.
