stm32h7:pinmap Remove GPIO_SPEED_xxx and add legacy pinmap

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

  This change adds CONFIG_STM32H7_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, STM32H7_USE_LEGACY_PINMAP will be deprecated and the legacy
  pinmaps removed from NuttX.

  Any new boards added should set STM32H7_USE_LEGACY_PINMAP=n and
  fully define the pins in board.h

In the past, pinmap files included GPIO_SPEED_xxxMhz. These speed
settings should have come from the board.h as it describes the wiring
of the SoC to the board. The speed is really slew rate control and
therefore is related to the layout and can only be properly set
in board.h.
STM32H7_USE_LEGACY_PINMAP is provided, to allow 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 output the required changes that one needs
to make to a board.h file.
