dts: hisi: fixes no syscon fault when init mdio

Browse Source 
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 dealt syscon, but dts doesn't.
It cause such fault, so this patch adds the syscon info on dts files to
fixes it.

Hisilicon HiP05 PERISUB system controller
Required properties:
- compatible : "hisilicon,hip05-perisubc", "syscon";
- reg : Register address and size
The HiP05 PERISUB system controller is shared by peripheral controllers in
HiP05 Soc to implement some basic configurations. The peripheral
controllers include mdio, ddr, iic, uart, timer and so on.
Example:
/* for HiP05 perisub-ctrl-c system */
peri_c_subctrl: syscon@80000000 {
compatible = "hisilicon,hip05-perisubc", "syscon";
reg = <0x0 0x80000000 0x0 0x10000>;
