    stmhal: Add stm module, which contains some constants for the MCU. · 3f489845

    Also contains raw memory read/write functions, read8, read16, read32,
    write8, write16, write32.  Can now do:
    
    stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)
    
    This turns on the red LED.
    
    With the new constant folding, the above constants for the GPIO address
    are actually compiled to constants (and the addition done) at compile
    time.  For viper code and inline assembler, this optimisation will make
    a big difference.  In the inline assembler, using these constants would
    not be possible without this constant folding.
