Some periph_rtt implementations do not provide `rtt_set_counter()`. This
adds `periph_rtt_set_counter` as feature to allow testing for its
availability. The feature is provided at CPU level if periph_rtt is
provided by the board for all CPUs implementing `rtt_set_counter()`.

Found and fixed the issue for the kinetis-based boards: The kinetis
code is using some macros to map some IRQ names, that differ in
some versions of vendor headers, to a RIOT wide unique name. The
doxygen of this mapping states, that this mapping must be done before
any vendor header is included. Unfortunately, the mapping was so far
placed in cpu/kinetis/vectors.c, before any other include statement.
In some cases, the vendor headers might be included before the
mapping macros in vectors.c, leading to the compilation errors down
the line. To fix this, the adaption defines are moved into
cpu/kinetis/cpu_conf.h, which is the file that actually includes
the vendor headers. This way it is ensured, that these adaption
macros are always defined before any vendor header is included,
and therefore preventing this kind of error for good.
CPU_HAS_SRAM_BITBAND can be used to check whether bit-banding is supported for
all of SRAM. With partially supported bit-banding, this feature is more of a
foot gun that a valuable tool.
MCG_Lite is used in many KL parts and is a less advanced clock generator
than the full MCG used in the K series. This change lets the MCG_Lite
and MCG share the same user facing API, with some configuration
differences.
Use RTC helper functions instead of libc functions.
This gives us y2038 safety by the extended epoch
and saves a good chunk of memory:

The spi scalar calculation tool for the kinetis family is stand-alone
and doesn't use the RIOT headers. It doesn't include the ARRAY_SIZE
macro from the RIOT headers. This commit adds a local definition of the
ARRAY_SIZE macro
Rename the variable to make it clearer that it refers to the last Makefile
included.
Usually this is the current file, but when another Makefile is included this
changes.
This moves the following modules to a architecture-specific Makefile.dep
file:
- cortexm_common
- cortexm_common_periph
- newlib
- newlib_nano
- periph
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.
