one bcm device the cisco meraki mx65 doesn't have them set.
no qca8327 device have them used.

device with qca,rgmii0-1-8v
netgear r7500v2
Askey RT4230W REV6

device with qca,rgmii56-1-8v
NEC Platforms Aterm WG2600HP3
TP-Link Talon AD7200
Qualcomm Technologies, Inc. IPQ8064/AP-148
AP-161
netgear d7800
dev board DB149
Linksys EA8500 WiFi Router
Linksys EA7500 V1 WiFi Router
ASRock G10
Netgear r7500
TP-Link Archer VR2600v
NEC Aterm WG2600HP
Compex WPQ864
Buffalo WXR-2533DHP

device with both enabled:
ZyXEL NBG6817
Netgear r7800

Here is the list I could have missed some user on the ath79 target but I
hope I made a point on how random this is and that we need dedicated
binding for this. Thanks for the review anyway.
