Merge #235
235: make 'fn ptr()' APIs to be 'const fn ptr()' r=therealprof a=JOE1994
This PR changes functions like `ITM::ptr()`, `DWT::ptr()` to become `const fn`s.
* functions like `ITM::ptr()`, `DWT::ptr()` return pointers that are cast from constants,
but currently these functions can't be used to define a constant. This PR will allow below code to compile.
```rust
use cortex_m::peripheral::ITM;
use cortex_m::peripheral::itm::RegisterBlock;
// Below line currently won't compile, since `ITM::ptr()` is not a `const fn`
const ITM_PTR: *mut RegisterBlock = ITM::ptr();
```
I couldn't think of disadvantages that might accompany this change, but please correct me if I'm wrong.
Thank you for reviewing this PR :+1:
