ravb: Duplex handling update V3

[PATCH v3 01/02] ravb: Do not announce HDX as supported
[PATCH v3 02/02] ravb: Clean up duplex handling

This series is V3 of duplex handling improvements for the Ethernet-AVB driver.

Previous versions of this series have been posted to linux-renesas-soc as RFC
so V3 is the first actual version to make it to netdev.

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 V2:
- Updated patch 1/2 to make use of phy_remove_link_mode()
- Added Reviewed-by from Sergei - thanks!

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

Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper")
