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.

Introduce SoC specific config options similar to what exists on NRF51,
this is mostly to help distinguish between SRAM & Flash sizes on
different variants.
Also deleted some unnecessary setting of CONFIG_SOC_NRF528{32,40} in the
board defconfig files.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

In preparation for the upcoming nRF52840 support, this patch refactors
the nRF52 series support code to allow for future members of the IC
family to be added, while keeping everything that is common together.

Quoting the product specification this device contains an "ARM
Cortex-M4 processor with floating-point unit" or, as this would
more normally be expressed an ARM Cortex-M4F.
Update Kconfig accordingly.
