====================
enc28j60: messaging clean up and ACPI improvements

Most of the patches in the series dedicated to update messaging to use modern
APIs, such as netdev, with a benefit to distinguish devices, if more than one
installed on the system.

Besides that, patch 1 targeting ACPI enabled systems when MAC address provided
there via properties.

And few clean ups are included, such as:
- switching to module_spi_driver()
- converting to use ether_addr_copy() API
- converting to use SPDX

Since v2:
- cover letter is added
