net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY
[ Upstream commit 69ff53e4a4c9498eeed7d1441f68a1481dc69251 ]
Jerome provided the information that also the GXL internal PHY doesn't
support MMD register access and EEE. MMD reads return 0xffff, what
results in e.g. completely wrong ethtool --show-eee output.
Therefore use the MMD dummy stubs.
Fixes: d853d145ea3e ("net: phy: add an option to disable EEE advertisement")
