Adding /wirish/boards/ for easier porting; shrank PIN_MAPs.

/wirish/boards/ contains xxx.h and xxx.cpp (for xxx=maple,
maple_native, maple_mini, maple_RET6).  The headers contain the
board-specific #defines that used to live in boards.h (except
BOARD_INIT, which was removed).  The CPP files contain the PIN_MAP
definitions that used to live in boards.cpp, and a proper boardInit()
function to replace the old BOARD_INIT macro.  This will make it
easier to add new boards in the future.

struct PinMapping was renamed struct stm32_pin_info, and was moved
into a new wirish_types.h.  Its external interrupt field was moved
into struct gpio_dev, which saves memory by storing an afio_exti_port
per port, rather than one per pin.  Also rearranged the stm32_pin_info
fields to improve packing.  Maple's PIN_MAP is now down to below 500
bytes.
