Reset the device on initializing if reset-node is available in dts.
`snps,desingware-i2c` does not define reset-node itself.
Add more of an element that inherits `reset-device.yaml` to
the `compatible` section to allow defining the reset-node
for using this feature.
For example.
```
compatible = "reset-device-inherit-node", "snps,designware-i2c";

This commit adds option to dump i2c messages of only specified
devices. It makes it easier to debug communication of specific
i2c device instead of logging all i2c communication.
The filter of devices is specifiec in device-tree using the
node with "zephyr,i2c-dump-filter" compatible string.
Example of device-tree node:
i2c-dump-filter {
compatible = "zephyr,i2c-dump-filter";
devices = < &display0 >, < &sensor3 >;
};

To be consistent with other xmc4xxx drivers.
A few other device tree changes:
- Rename clock signal option as it's handled by DX1.
- Remove clock-frequency option as it's already added in

Currently the driver is not configured as controller during initialization.
Any use of I2C in controller mode without an explicit i2c_configure() will
not work.
In this commit the driver is automatically configured.
But, delay the configuraition until first use instead of during init
because otherwise tests/drivers/i2c/i2c_target_api hangs without any
errors on xmc47_relax_kit (when internal pulls are used). This issue
needs to be investigated.
There are a few other fixes/cleanups:
- Change the default master_frequency from XMC4_I2C_SPEED_STANDARD to
I2C_SPEED_STANDARD.
- Use devicetree clock frequency for target configuration instead of
I2C_SPEED_STANDARD.
- Rename master_frequency to bitrate as it's also used by the target
configuration now.
- Remove several uneeded casts.
- Forward backup config in get_config().

Sometimes, channel C may write wrong register to the target device.
This issue occurs when FIFO2 is enabled on channel C. The problem
arises because FIFO2 is shared between channel B and channel C.
FIFO2 will be disabled when data access is completed, at which point
FIFO2 is set to the default configuration for channel B.
The byte counter of FIFO2 may be affected by channel B. There is a
chance that channel C may encounter wrong register being written due
to the FIFO2 byte counter wrong write after channel B's write operation.
The current workaround is that channel C cannot use FIFO mode.

The memory-region is not required property that enables user

The eSPI, I2C, and SPI emulators use devicetree macros to build an array
of devices on the virtual bus. Currently, they will add device nodes that
are not status-okay. This leads to linker errors because the respective
device drivers would not have instantiated device structs for these
nodes --assuming the driver was even compiled. This can be frustrating
if nodes need to be disabled for debugging or configuration purposes.
Update the bus emulators to only consider status-okay nodes by changing
the macros used to iterate over bus devices.

The NPCX I2C controller has a port-controller hierarchy and the driver
is split in two files, with separate device struct and init functions.
These are currently initialized at the same level and priority, so the
actual order depends on what the linker does.
To avoid relying on the linking order, add a dedicated priority option
for the port that is set to go after the normal I2C one by default.
Found this by building with CONFIG_CHECK_INIT_PRIORITIES.
