    Fix stm32f3discovery flash programming
    
    Fixes two issues:
    
    1) Flash size was declared with the wrong size; since the bsp partitions
       where declared inside the valid flash size this fix is only for
       correctness.
    2) Re-enable HSI clock. The flash programming interface on the F3 family
       is directly connected to the HSI clock generator, so without it
       enabled, trying to run any app that requires flash programming (eg
       slinky) would result in a hardfault.
