Joakim Nohlgård c7801e466d kinetis: Refactor RTT driver
- Keep counter value between resets
- Let kinetis_mcg_init manage the RTC oscillator, to avoid disrupting
  the core clock in certain configurations
- Remove some unnecessary macros for hardware abstraction; all Kinetis
  CPUs which have an RTC only have a single RTC instance, and the ISRs
  and hardware registers are named the same way in all Kinetis CPU
  headers.
