The old CONFIG_UART_NS16550_ACCESS_IOPORT has been used to
indicate whether to access the NS16550 UART via IO port
before device tree is used to describe hardware. Now we have
device tree, and we can specify whether a particular UART
needs to be accessed via IO port using property io-mapped.
Therefore, CONFIG_UART_NS16550_ACCESS_IOPORT is no longer
needed (and thus also CONFIG_UART_NS16550_SIMULT_ACCESS).
Remove these two kconfigs and modify code to use device tree
to figure out how to access the UART hardware.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

The XY Memory is a feature commonly found in DSP processors to increase
the DSP performance. The XY component allows a ARC processor to
implicitly load source operands and store results into a closely coupled
memory using a single instruction.

em_starterkit_em11d. emsdp_em9d, nsim_em, iotdk.

ARC processors are highly configurable, so ARC toolchain supports
big amount of mcpu options for all that HW configurations.
As difference in many configurations among the same processor
family usually doesn't affect Zephyr code we don't want
to create Kconfig option for each possible CPU configuration
(just to map Kconfig option to correspondent mcpu value
in 'cmake/gcc-m-cpu.cmake').
Instead we prefer being able to set proper mcpu value
individually for any ARC SoC and using 'cmake/gcc-m-cpu.cmake'
just for reasonable defaults.
To apply SoC-related changes for build-options on early stages of building
'tune_build_ops.cmake' should be created in appropriate SoC directory.
Example:
./soc/arc/snps_qemu/tune_build_ops.cmake
File content:
set(GCC_ARC_TUNED_CPU hs4xd)

The soc.c source only contains code relevant to SMP, and in fact, it is
a file that is left empty when pre-processed from a compiler perspective
if CONFIG_SMP=n. This change renames it to smp.c to make it clear it
contains SMP related code, and, it compiles it conditionally to
CONFIG_SMP=y.

The HAS_I2C_DW was to limit Kconfig visibility to only platforms
that utilize the I2C DW IP. The Kconfig for I2C_DW depends on
DT_HAS_SNPS_DESIGNWARE_I2C_ENABLED which will cause the same
visbility limitation to only platforms that have I2C DW devicetree
nodes. Thus we can remove HAS_I2C_DW and its references.

Now that serial drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by
Kconfig.defconfig* files as this can lead to errors.
Typically the Kconfig.defconfig* will blindly enable a
sensor and not respect the devicetree state of the serial.
Additionally we can get problems with prj.conf/defconfig
getting incorrectly overridden.

Currently we use incorrect memory layout for SMP boards as
we put data (which need do be accessible from all cores) to
DCCM which is private for each CPU core.
This works for nSIM which doesn't simulate CCMs (as we don't pass
corresponding nSIM options for SMP configurations) however
it won't work if we run that code on real HW (we want to achieve
that nSIM configurations are also runnable on HAPS - FPGA platform).
Let's fix that issue by using DDR instead of CCMs for SMP
configurations (nsim_hs_smp and nsim_hs6x_smp).
While I'm at it - switch UP HS6x configuration (nsim_hs6x)
for DDR usage instead of CCMs - to make that configuration closer
to the HAPS config we have.
