tinyusb: Add hardware initialization for STM32F4xx STM32L4xx
This provides code for hardware initialization.
Part of this initialization is present in tinyusb bsps which
are not used by mynewt since it has own bsps.

+ Set this to 1 if hardware has external pull up resistor.
+ Synopsys does have internal pull up that allows to re-enumarate
+ without physical disconnection, but it will not work when
+ external pull up is present (like on on black_vet6 board).
+ Setting this changes pin to GPIO 0 at startup for a fraction
+ then device is discovered by host.
