Introduce nrfx_nvmc driver into nordic flash driver implementation.
Thanks to that nrf9160 SoC becomes supported by the driver.
nrfx helps dealing with differences with interface to the NVMC
in secure and non-secure execution modes.
This patch adds NRFX_NVMC Kconfig entry for enabling nrfx_nvmc and
select it along with nordic flash driver.
Disabled UICR operation on nRF9160 for non-secure build
as UICR is not available in this mode.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

An external project extending the Zephyr RTOS and its drivers may have
subsystems that must use its own specific driver(s) when active. One
example is the nRF5x NVMC that must be scheduled in between radio
operations. A subsystem may also be dependent on its own drivers for
security, real-time and/or because of hardware constrains.
In order to not introduce non-Zephyr specific code into the Zephyr tree,
an option is added to disable the in-tree drivers in Zephyr. Because
Kconfig does not support a good way of de-selecting other symbols, a
variable on the form `<DRIVER>_FORCE_ALT` is added as a
dependency for each `<DRIVER>`. For example, the out-of-tree subsystem
will select `FLASH_NRF_FORCE_ALT` to disable the in-tree driver. A
solution for issue #8181 would open up for a more general solution,
however #8181 requires significant effort.
Support for out-of-tree drivers is added to Nordic drivers for
clock_control, entropy and flash.
A generic solution for this is desired. Issue #14527 is tracking that
progress.

Redefining the config will not let another (out-of-source) driver be
chosen instead of the default. The driver is practically forced by the
soc settings. This commit moves default settings from soc/arm/nordic_nrf
into the drivers themselves.

Cleanup the Kconfig code for the flash driver. Platform-specific
options should be in their own Kconfig files to be consistent and to
not pollute the common configuration.
To this end we move the nrf options into it's own file.
