dwc2: Using internal phy (fs mode) for STM32F4x9 platform

Hello all, I'm bringing the linux kernel for the STM32F4 MCU (mmu-less). This MCU has two DWC2 cores on it:one for USB OTG HS and one for USB OTG FS. I was able to make the DWC2 driver to work in FS mode using a internal phy in both cores (HS and FS), but I had to patch it (in a bad way, see bellow
