This commit contribute an internal ARM API that enables the
user to confgure an ARM Security Attribution Unit region. It
also defines ARM_SAU as a K-config option to indicate that
an MCU implements the ARM SAU.

Make GCC compile with the -mcmse compile option, if we are
building a Secure firmware. The option will make Security
Extensions for secure executables available, and will set
the corresponding compile-time indicator flag, accordingly:
(i.e. __ARM_FEATURE_CMSE=3).

In most Nordic SoCs the SPI and TWI peripherals with the same instance
number share certain resources and cannot be used at the same time.
In nRF52810 there are only single instances of these peripherals and
they are arranged in a different way so this limitation does not apply.

zephyr_library_compile_options will apply compile options to a library
with high priority. Due to bug #8438 these compile options have been
applied not only to the library, but also to it's public interface and
therefore to any library that has been linking with the library.
To resolve#8438 we use PRIVATE linking instead of PUBLIC linking.

This finishes refactor of splitting off net_config library name from
net_app library, started in c60df1311, c89a06dbc. This commit makes
sure that Kconfig options are prefixed with CONFIG_NET_CONFIG_
instead of CONFIG_NET_APP_, and propagates these changes thru the
app configs in the tree.
Also, minor dependency, etc. tweaks are made.

User mode may now access the read, write, and trigger APIs.
Unlike supervisor mode, memory slabs are not dealt with directly,
the data is always copied.
A new driver API added to fetch the current channel configuration,
used by the system call handlers.
The i2s_sam_ssc driver updated for the new API. CAVS driver not
modified as there is no user mode port to Xtensa yet.

We use the code generator 'gen_syscalls.py' to assign numeric
id's to each syscall. These id's have been defined using an enum
like this:
enum {
K_SYSCALL_ADC_DISABLE,
K_SYSCALL_ADC_ENABLE,
K_SYSCALL_LIMIT
};
but enums can not be included by assembly files. So we have been
compiling the enum values and then extracting them into #define's when
needed.
In this situation there happen to not be any benefits of using
'enum' over #define's so we can simplify by initially defining
them with #define instead.

The testcase was using only SYS_LOG_ERR() to signal error conditions,
which would print useful error information to the console, but allow the
test to pass when it should fail. Add zasserts after every SYS_LOG_ERR()
to make the test fail properly.

This commit removes redundant reads of RTC_COUNTER register
propagating optimizations made in the k_cycle_get_32() function.
Signed-off-by: Piotr Zięcik <piotr.ziecik@nordicsemi.no>
The previous implementation of _timer_cycle_get_32() (which is directly
mapped to k_cycle_get_32()) taken from 87 to 132 cycles. As result it
was too heavy for using it as source of time for logger.
This commit makes this function faster by removing redundant access
to the RTC register (each access consumed 28 CPU cycles) as well as
loop, which made this call non-deterministic.
After these changes the k_cycle_get_32() needs only 50-52 cycles
in to calculate 32-bit timestamp.
