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 >;
};

Use allowlist to specify which devices transactions should be logged.
|

The allowlist is defined in the devicetree using the compatible string of
|
|
"zephyr,i2c-dump-allowlist" and phandles to the devices that need to be traced.

Example of devicetree node:
