Add a shim layer around the ksdk I2C driver to adapt it to the Zephyr
I2C interface. Currently only supports master mode.

The ksdk provides a clock driver, fsl_clock.c, for the K64F and an
example usage of that driver, clock_config.c, for the Freedom board.
See ext/hal/ksdk/devices/MK64F12/
Leverage parts of clock_config.c to configure the clocks (specifically,
the sequence in BOARD_BootClockRUN()), but use the new Kconfig options
to set up the configuration structure. This will allow support for new
boards that may have a different external oscillator frequency or type.

Many Kinetis SoCs contain an Oscillator (OSC) module and a Multipurpose
Clock Generator (MCG) module to configure clocks. Adding options to
configure these modules for PLL operation with different external
oscillator frequencies, which can vary across boards. More options may
be added later to support other clocking modes such as FLL.

The K64F SoC initialization previously used macros and structs
custom-defined in Zephyr in order to access peripheral registers.
Refactored it to use CMSIS-style register accesses from the ksdk
instead.

Adds Kconfig options CPU_HAS_FPU, FLOAT and FP_SHARING for the arm
architecture.
NOTE: All SOCs in the MK64F12 family have an FPU so that makes it a
convenient location to enable the hidden CPU_HAS_FPU option.

The KSDK device header files require a preprocessor macro that defines
the part number string (e.g., MK64FN1M0VMD12). Create a hidden Kconfig
option to hold the part number string, and hidden Kconfig options that
the board Kconfig will use to select the specific part number.

Moved setting of specific Cortex-M compiler flags in each SoC directory
unify setting them in the arch/arm/soc Makefile.
Add flags for Cortex M0, M0+, M1, M3, M4, and M7. However only
CONFIG_CPU_CORTEX_M3 and CONFIG_CPU_CORTEX_M4 are supported at this time
As part of this change converted Kbuild files for some SoCs into
Makefiles as the Makefiles would be empty otherwise.

Introduce a soc-cflags, soc-cxxflags, and soc-aflags as a means for
SoC specific compiler flags to be set without manipulating Kbuild
options directly.

cover all the places where these files are found. At least in
VIM, these files are now syntax highlighted correctly.

The UART console init should be done after UART init. So it can be
folded into general UART init, thus one fewer SYS_INIT().

The clkInit() is always called so this can be inlined.
This saves 32 bytes of ROM space compared to non-inlined version.

It was not possible to add directories under an SoC family
because of the direct call to Makefile in the SoC series from the
architecture level.
While we have SoC still using the old structure, add a conditional
to still support old structure and allow Makefiles directly under
an SoC family directory.
This is useful for adding drivers and BSP files common to one family.

Add Kinetis SoC family and rename fsl_frdm_k64f to mk64f12.
This will allow adding new SoCs of the same family and the reuse of code
among SoCs of the family and series.
