dt-bindings: arm: hisilicon: delete the descriptions of HiP05/HiP06 controllers

The compatible strings of Hi6220 SRAM controller, HiP05/HiP06 PCIe-SAS
subsystem controller, HiP05/HiP06 PERI subsystem controller and
HiP05/HiP06 DSA subsystem controller is in syscon.yaml now.

-Hisilicon Hi6220 SRAM controller
-
-Required properties:
-- compatible : "hisilicon,hi6220-sramctrl", "syscon"
-- reg : Register address and size
-
-Hisilicon's SoCs use sram for multiple purpose; on Hi6220 there have several
-SRAM banks for power management, modem, security, etc. Further, use "syscon"
-managing the common sram which can be shared by multiple modules.
-
-Example:
-	/*for Hi6220*/
-	sram: sram@fff80000 {
-		compatible = "hisilicon,hi6220-sramctrl", "syscon";
-		reg = <0x0 0xfff80000 0x0 0x12000>;

-The PERI sub system controller is shared by peripheral controllers in
-HiP05 or HiP06 Soc to implement some basic configurations. The peripheral
