* system timer simplfication
* Removes _all_ type params on Alarm
* Systimer no longer implements peripheral ref, the peripheral ref
pattern is instead intended to be used on the higher level timer
drivers
* Removed `Unit` as a type, in favour of an enum
* Alarms are back in the main `SystemTimer` "driver"
* Made all `Unit` modification methods unsafe, it's not possible to
modify the `Unit`'s safely whilst timers and or the `time::now` API is
in use
* fix examples and tests (by removing them :D)
* changelog and migration
