altos: Make STM clock configuration per-product. Fix 32MHz CPU speed
This moves all of the STM clock configuration into ao_pins.h so that
each product can configure it separately. While doing this, I
discovered that the flash memory mode (64-bit, prefetch, latency 1)
wasn't actually getting set, which is why the CPU refused to work at
32MHz.
