Patch List:

   *Current implementation of LL_SPI_TransmitData16 on F3/F7/L4 family
    generates following warning:
    "warning: dereferencing type-punned pointer will break strict-aliasing
    rules [-Wstrict-aliasing]"
    Besides being forbidden by rule, this cast is not needed, as register is
    16 bits wide. Modification has been tested on L4 SoC.
    stm32yyxx_ll_spi.h being included in soc.h file, warning is generated
    at each compiled object, this commit allows a clean build.

    ST Bug tracker ID: 13359


   *Disable new CAN API and enable Legacy API
     A new CAN API has been delivered on recent F7 stm32cube.
     This new API breaks current CAN driver. Disable the new API and enable the
     legacy API.
     Disable related systematic warning message

   *Fix LL_EXTI_LINE_18 and LL_EXTI_LINE_20 declarations
     LL_EXTI_LINE_18 and LL_EXTI_LINE_20 are declared in stm32f7xx_hal_pcd.h
     and in stm32f7xx_ll_exti.h which generates warnings. Set #ifndef
     in stm32f7xx_ll_exti.h around declarations.

    *Use of (__packed uint32_t *) produces warning
      Using GNU 8.2.0, (__packed uint32_t *) generates warning.
      Replace with CMSIS macros __UNALIGNED_UINT32_READ and
      __UNALIGNED_UINT32_WRITE.
