Add the EMAC GDSCs to allow the EMAC hardware to be enabled.

Acked-by: Stephen Boyd <sboyd@kernel.org>

I'm still unsure if Bjorn wants to take this patch or net-dev, and how I am
supposed to indicate such other than commenting here (per Stephen's
comment on v1): https://lore.kernel.org/netdev/e5cb46e8874b12dbe438be12ee0cf949.sboyd@kernel.org/#t

Changes since v1:
	* Add Stephen's Acked-by
	* Explicitly tested on x13s laptop with no noticeable side effect (Konrad)
