arm64: dts: renesas: spider: Add Ethernet sub-board

Browse Source 
Add a DTS file for the Spider Ether TSN sub-board (RTP8A779F0ASKB0ST0S),
and include it from the main r8a779f0-spider.dts.

For now its contents are limited to the Board ID EEPROM.

Extracted from a larger patch in the BSP by LUU HOAI.
