Subject: [PATCH 18/19] stmmac: dwmac-sti: Remove obsolete STi platforms

This patch removes support for STiH415/6 SoC's from the
dwmac-sti driver and dt binding doc, as support for these
platforms is being removed from the kernel. It also removes
STiD127 related code, which has never actually been supported
upstream.

  - st,gmac_en: this is to enable the gmac into a dedicated sysctl control
