Spencer Oliver d631b2e5ac flash: add stm32lx loader Hard Fault workaround 
An issue has been seen with the stm32lx flash driver that if a
power cycle/reset is applied after a erase, any ram loader will Hard Fault
on execution.

A similar issue is mentioned in the errata for the device.
Two solution's seem to workaround this issue:
1, Handle the exception, this means adding exception vectors to the loader
   and changing the exception address using nvic vtor register.
2. falling back to using slower direct page writes - approx 50% slower.

Using solution 1 would mean restrictions are placed on the loader location.
Solution 2 was chosen mainly as it was simpler too implement.
