Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.

irq_lock returns an unsigned int, though, several places was using
signed int. This commit fix this behaviour.
In order to avoid this error happens again, a coccinelle script was
added and can be used to check violations.

The imxrt1050 is configured to use SYSTICK for the kernel timer, but
SYSTICK cannot wake up the soc from low-power modes. Disable low-power
modes on this soc until we have support for an alternative timer.
This fixes k_sleep on the EVKB version of the mimxrt1050_evk board. An
earlier version of the board (EVK, not EVKB), had A0 silicon which
by default did not enter low-power mode on a wfi.

An issue has been confirmed in CMSIS core header file in
SCB_EnableDCache when stack is in cacheable memory.
Issue report: https://github.com/ARM-software/CMSIS_5/issues/331
To workaround this issue by checking if Dcache's been enabled before
trying to enable it.

Adds the mimxrt1052 SoC, which belongs to a new family (nxp_imx) and
series (rt) of SoCs. The mimxrt1052 integrates an Arm Cortex-M7 core,
512 KB TCM, and many peripherals including 2D graphics, an LCD display
controller, camera interface, SPDIF and I2S. Unlike other SoCs in
Zephyr, the mimxrt1052 has no internal flash.
This initial port to mimxrt1052 configures the system clock to operate
at 528 MHz, and enables the serial/uart and gpio interfaces to support
the hello_world and blinky samples. Support for additional Zephyr driver
interfaces will come later.
