[PATCH net-next 2/3] dts: hisi: fixes no syscon error when init mdio

[yankejian]

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.
