arch: stm32l4: only enable USB OTG on SoCs supporting it

Browse source 
USB OTG is currently enable for the whole STM32L4 family, while only a
few of them actually support it:

- STM32L475, STM32L476 and STM32L496 have an OTG controller
- STM32L432, STM32L433 and STM32L452 have an USB controller
- STM32L431, STM32L451 and STM32L471 do not have any USB controller

Fix that by moving the DT entry from stm32l4.dtsi to stm32l475.dtsi
and by adding a #ifdef #endif around the corresponding DTS fixup
entries.
