Subject: [PATCH] arm64: dts: meson: add dwmac-3.70a to ethmac compatible list

After discussing with Amlogic, the Synopsys GMAC version used by
the gx and axg family is the 3.70a. Set this is in DT

 Hi,

 The same should be true for the meson8 families but I did not test
 it which is why only the patch only address the 64bits SoC families
