net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY

Browse source

[ Upstream commit 69ff53e4a4 ]

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: d853d145ea ("net: phy: add an option to disable EEE advertisement")
