We now have generic ARM M4 MPU support added to Zephyr.
Let's enable it for use with Nordic nRF52 chips.
Memory Layout was generated from Section 8.3 "Memory
Map" of nRF52 Product Specifications (for both nRF52832
and nRF52840):
0x00000000: Flash
0x10000000: Factory Information Config Registers
0x10001000: User Information Config Registers
0x20000000: SRAM
0x40000000: APB Peripherals
0x50000000: AHB Peripherals
0xE0000000: ARM M4 Private Peripheral Registers
NOT Configured:
0x60000000: External RAM
0x80000000: External RAM
0xA0000000: External Device
0xC0000000: External Device
NOTE: More work will be needed for future Nordic MWU (Memory
Watching Unit) support.

Now that all ARM platforms have a device tree we can move selecting of
HAS_DTS up and remove any !HAS_DTS cases, as well as setting in all the
defconfigs.

Add device tree support for Nitrogen 96board, BLE Nano 2, and
nRF52-PCA10040 DK boards. This is minimal support for memory, flash,
and UART.
For the nRF52832 we select between "nordic,nrf-uarte", "nordic,nrf-uart"
support for each board.

Introduce an architecture sorting of boards. This is to allow for
easier maintenance going forward as the number of boards grows. It
will be easier for any scripts to know the board/arch mapping without
having to maintain an explicit list of what boards are associated with
which arch. We can also do things like have architecture maintainers
cover reviews and branches for arch/${ARCH} and boards/${ARCH} going
forward.
