Clean all of the RCC configuration up after turning on the clocks.
Use the MSI clock during initialization to avoid messing around with
the HSI clock temporarily.
Allow for an external clock on the HSE line.

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.

This runs AltOS and talks over the serial port.

The stm-bringup doesn't run altos, it just initializes the device and
writes stuff over a serial port. Works on the STM32L Discovery board
at least, should do stuff on other boards too.
