this patchset fixes the bug that eth can't initial successful on hip05-D02
because the dts files doesn't match the source code.

this patch enables the ethX for D02 board on hip05-d02.dts. otherwise it
cannot find hns ethX by ifconfig -a.

when linux start up, we get the log below:
"Hi-HNS_MDIO 803c0000.mdio: no syscon hisilicon,peri-c-subctrl
mdio_bus mdio@803c0000: mdio sys ctl reg has not maped "
the source code about the subctrl is dealled with syscon, but dts doesn't.
it cause such fault. so this patch adds the syscon info on dts files to
fixes it.

The compatible string in the example does not match the required properties.

I don't see the subctrl_vbase property documented in the binding. Please
modify the binding as well.
Also, please use the normal naming conventions using '-' instead of '_'
inside of property names.
