new 478f3bc39 tinyusb/synopsys: Add support for ULPI interface
478f3bc39 is described below

tinyusb/synopsys: Add support for ULPI interface
TinyUSB supports High Speed for STM32H7 with
external ULPI interface.
This adds support for this functionality.
When USB_USE_OTG_HS_ULPI syscfg value is 1
external PHY will be used instead of embedded FS PHY.
