Thanks for your patch!

This auto-enables DWMAC_RENESAS_GBETH when building a kernel for e.g
RZ/N1D, which uses stmmac with DWMAC_RZN1. So I'll have to disable
this explicitly in shmobile_defconfig. This is not a big issue,
we already have similar constructs (DRM_RCAR_USE_MIPI_DSI defaults to
DRM_RCAR_DU, but is not used on R-Car Gen1/2).
