[OpenWrt-Devel] [RFC v2 2/6] ar71xx: Save GMAC id in ag71xx_platform_data

[Sven Eckelmann]

From: Sven Eckelmann <sven.eckelmann at open-mesh.com>

The ag71xx driver must know which GMAC is is currently handling to enable
some special workarounds for this GMAC. GMAC0 has some registers on
QCA9558 which GMAC1 doesn't have.

 - Split into multiple patches and adjust slightly to look more like an
   OpenWrt patch
