Merge #607

607: stm32: Add standard crate-wide macros for pin/dma traits r=Dirbaio a=Dirbaio

All drivers will declare the traits using these macros.

This has a few implications:
- ALL drivers will have an Instance trait, even for drivers that usually have only one instance (for example crc, eth)
- It's no longer possible to have a fn configure() in pin traits, drivers will have to do that some other way

In the future, build.rs will generate all the impls instead of macrotables.

Pin/Dma traits are no longer explicitly sealed, since gpio::Pin and dma::Channel are already sealed, which has the same effect. This means the `af_num()` and `request()` funcs are now public, but IMO that's okay, they're unlikely to change.
