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:
|

i2c-dump-allowlist {

compatible = "zephyr,i2c-dump-allowlist";

devices = < &display0 >, < &sensor3 >;
