stm32:stm32f3{0|3|7}xxx pinmap Remove GPIO_SPEED_xxx and add legacy p…

…inmap

   Pinmaps should not have contained GPIO_SPEED_xxx settings.
   This is board dependent.

   This change adds CONFIG_STM32_USE_LEGACY_PINMAP to allow for
   lazy migration to using pinmaps without speeds.

   The work required to do this can be aided by running tools/stm32_pinmap_tool.py.
   The tools will take a board.h file and a legacy pinmap and outut the required
   changes that one needs to make to a board.h file.

   Eventually, STM32_USE_LEGACY_PINMAP will be deprecated and the legacy
   pinmaps removed from NuttX.

   Any new boards added should set STM32_USE_LEGACY_PINMAP=n and
   fully define the pins in board.h
