Subject: [PATCH 2/2] arm: hisi: enable Hi3521a soc

Enable Hisilicon Hi3521A/Hi3520DCV300 SoC. This SoC series includes
hardware mutlimedia codec cores, commonly used in consumer cctv/dvr
security systems and ipcameras. The arm core is a Cortex A7.

Add hi3521a.dtsi and hi3521a-rs-dm290e.dts for RaySharp CCTV systems,
marketed under the name Samsung SDR-B74301N.
