Dario Nieuwenhuis e8474426d8 hal-internal: remove impl DerefMut for PeripheralRef.
if you have `PeripheralRef<'a, AnyPIn>` for pin A, and `AnyPin` (owned) for pin B, you can `mem::swap` them.
so, getting access forever to pin A, just by "sacrificing" pin B

this defeats the point of PeripheralRef, which is if you got a `PeripheralRef<'a, T>` then you're only allowed to use the peripheral for `'a`.

Also some drivers rely on the fact only one instance of a singleton exists for soundness, so this is a soundness fix for those.

Internal implementation details for Embassy HALs. DO NOT USE DIRECTLY. Embassy HALs (embassy-nrf, embassy-stm32, embassy-rp) already reexport everything you need to use them effectively.
