93788ecced cpu/kinetis/Makefile.features: Use CPU_MODEL to determine features 
Now that CPU and CPU_MODEL are defined in the board's Makefile.features
it can be used to determine the available features provided by the
specific model.

cpu: Moved stdio_init() into cpu_init() 
- Removed stdio_init() from newlib's _init(), as this is too late in the boot

2de4b3011b periph_common: add as dependency to periph drivers 
Rational: the periph_common module is required by (most) other periph drivers
and also during startup of the CPU/MCU to run periph_init. The latter is only
required if other periph drivers are used, hence periph_common should be a
depency of periph_* modules and *not* of the CPU/MCU. This PR fixes that
by making periph_common a depency of periph_* and removing the explicit
include in the CPU/MCU implementation.

kinetis: save 'wdog-disable.bin' binary in the repository 
Keep the compiled '.bin' file to remove the need to compile it when
flashing. This remove the need to have the toolchain when flashing so
allow compiling and flashing with `BUILD_IN_DOCKER=1` without a local
toolchain.

Even if it ends up storing a binary, the file is only 34 bytes.

c219fdc001 kinetis/check-fcfield: skip on IMAGE_OFFSET > 0x410 
- fcfield is located in memory at 0x400-0x40f. Its content is only read
  upon reset, therefore if in presence of a bootloader and multiple
  applications, the fcfield will only be read when the bootloader
  is loaded. As long as we flash at IMAGE_OFFSET > 0x410 we do not
  care about the fcfield content since it won't get overwritten.

kinetis: move filtering-out periph_hwrng in cpu/kinetis 
This removes doing `filter-out periph_hwrng, $(FEATURES_PROVIDED)`
after processing `cpu/$(CPU)/Makefile.features`.
The current solution is a HACK as `CPU_MODEL` is currently not available
at that moment but will be in the near future.

It will allow always including `cpu/$(CPU)/Makefile.features` after
`boards/$(BOARD)/Makefile.features`.

It is a part of moving `CPU/CPU_MODEL` definitions to `Makefile.features`.

fa3b9168a0 kinetis: lptmr reload instead of spinning 
Spinning for the correct time has the side effect that it may cause
infinite recursion if the callback function calls timer_set.

timer_set->callback->...->timer_set->callback->...->timer_set-> infinity

In theory, the drawback is that the callback for very short timeouts
(<2 lptmr ticks) may be delayed up to 2 lptmr ticks (61 µs)

In practice however, tests performed using tests/bench_timers shows that
this change only affects the accuracy of the timer target when timer_set
is called with a timeout of 0, which results in a delay of 30 µs.

158a8300c4 kinetis: LPUART: Compute oversampling rate at init 
By not forcing a fixed oversampling rate we can achieve better baud rate
accuracy than otherwise possible.
For example, when requesting 115200 with a module clock of 4 MHz,
picking an oversampling rate of 17 (instead of hardware
default 16) yields 117647 baud instead of 125000 baud as the best
matching rate. Better matching baud rate between receiver and
transmitter results in a lower probability of transmission errors.
