sunxi: Fix H3 EMAC syscon register address

The sun8i-emac driver follows an old version of the proposed DT
bindings, where the EMAC clock and EPHY control register range is
listed directly, rather than through a syscon phandle.

Add back the syscon register range to avoid an invalid data access.
We should fix the driver once the Linux kernel bindings have been
finalized.
