ravb: Duplex handling update V2

[PATCH/RFC v2 01/02] ravb: Do not announce HDX as supported
[PATCH/RFC v2 02/02] ravb: Clean up duplex handling

This series is V2 of prototype-level code to update the Ethernet-AVB
driver to improve duplex handling.

Based on the latest data sheet for R-Car Gen3 [1] and R-Car Gen2 [2]
the following information is part of the EthernetAVB-IF overview page:

Transfer speed: Supports transfer at 100 and 1000 Mbps
Mode: Full-duplex mode

It seems that the driver implementation is not matching the information
provided in the friendly data sheet, and on top of this during run-time
when changing PHY configuration of the link partner the Ethernet-AVB PHY
seems to want to announce unsupported modes.

[1] R-Car Series, 3rd Generation Rev.1.00 (Apr 2018)
[2] R-Car Series, 2nd Generation Rev.2.00 (Feb 2016)

Changes since V1:
- Updated patches to reflect input from Sergei and Geert - thanks!

Getting closer to be suitable for upstream merge?
