Add __name__ to all board modules

[jepler]

@capellini noticed that (most?) boards don't have __name__ in the board module: #5183 (comment)

It would be good to see this added, just for consistency's sake.

Hi, I would like to work on this. Can you suggest me ways to get started?

Take a look at #5222, which added board.board_id. The author wrote a script to automate the changes.

@PracticalMetal We want add a __name__ attribute and assign it a q-string value of 'board', since that's the name of the module. So that, at the serial terminal, instead of getting a blank name for the module:

>>> import board
>>> board
<module ''>

we would get 'board' instead:

>>> import board
>>> board  # the next line prints 'board' instead of a blank string
<module 'board'>

Inside the pins.c file for each board (ports/**/boards/**/pins.c), we would need to change the board_global_dict_table (sometimes named board_module_globals_table) to add the following line:

STATIC const mp_rom_map_elem_t board_global_dict_table[] = {
    { MP_ROM_QSTR(MP_QSTR___name__), MP_ROM_QSTR(MP_QSTR_board) }, // this line needs to be added to each file
    // ...

provided that you have access to a terminal, you can use a utility likesed to do an in-place substitution, where we insert the line above in the first line of the board_global_dict_table definition:

sed -i \
   's/STATIC const mp_rom_map_elem_t board_global_dict_table\[\] = {/STATIC const mp_rom_map_elem_t board_global_dict_table\[\] = {\n    { MP_ROM_QSTR(MP_QSTR___name__), MP_ROM_QSTR(MP_QSTR_board) },/' \
  ports/**/boards/**/pins.c

You could also do the same for files that use board_module_globals_table instead of board_global_dict_table. Then it should be a matter of making sure that sed put the correct lines in.
