This patch adds the arm core MPU interface, a common way to access the
pu functionalities by the arm zephyr kernel.
The interface can be divided in two parts:
- a core part that will be implemented by the arm_core_mpu driver and
used directly by the kernel
- a driver part that will be implemented by the mpu drivers and used by
the arm_core_mpu driver

This patch adds initial MPU support to NXP K6x family.
The boot configuration prevents the following security issues:
* Prevent to read at an address that is reserved in the memory map.
* Prevent to write into the boot Flash/ROM.
* Prevent from running code located in SRAM.
This driver has been tested on FRDM-K64F.

It is useless to include the pinmux for a peripheral if it is not
enabled in the Kconfig. This is unnecessary and it increases the size of
the binary.
Define macros that will default to void if the associated Kconfig is not
enabled.

Clean-up the pinmux arrays as a preparatory work before adding more
pinmuxes.
This is achieved by the following two actions:
- Define the PAD macro to simplify the [x - 1] = y construct
- Reorder the declartions by bank / pin to make it easier to
locate a pin among a high number of other pins, while minimizing the
risk of conflict when two people add a new declaration for two
different pins

Unline k_thread_spawn(), the struct k_thread can live anywhere and not
in the thread's stack region. This will be useful for memory protection
scenarios where private kernel structures for a thread are not
accessible by that thread, or we want to allow the thread to use all the
stack space we gave it.
This requires a change to the internal _new_thread() API as we need to
provide a separate pointer for the k_thread.
By default, we still create internal threads with the k_thread in stack
memory. Forthcoming patches will change this, but we first need to make
it easier to define k_thread memory of variable size depending on
whether we need to store coprocessor state or not.
