net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY
[ Upstream commit69ff53e4a4
] 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
