kernel: add Microchip ENC28J60 SPI Ethernet controller module

The ENC28J60 is a 10 Mbps half-duplex Ethernet controller interfaced via SPI.
It achieves real-world bandwidth up to 5Mbit/s on devices like the RPi Zero due
to SPI limits.
Commonly used with Raspberry Pi Zero boards for wired network connectivity.
