This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.
The "pin_obj_t" structure, holding pin information, had an unused
word-sized field ("pull") that isn't used by any of the board
definitions, yet it takes up space in each pin structure being compiled
in the final firmware image.
Images for all available boards were built successfully with this
change, so there should be no unwanted issues arising from shrinking
that structure.
