esp32/main: Add option for a board to hook code into startup sequence.

Browse Source 
To do this the board must define MICROPY_BOARD_STARTUP, set
MICROPY_SOURCE_BOARD then define the new start-up code.

For example, in mpconfigboard.h:

    #define MICROPY_BOARD_STARTUP board_startup
    void board_startup(void);

in mpconfigboard.cmake:

    set(MICROPY_SOURCE_BOARD
        ${MICROPY_BOARD_DIR}/board.c
    )

and in a new board.c file in the board directory:

    #include "py/mpconfig.h"

    void board_startup(void) {
        boardctrl_startup();
        // extra custom startup
    }

This follows stm32's boardctrl facilities.
