Subject: [PATCH v7 2/7] MIPS: Loongson: ls7a-pch.dtsi: add has_dedicated_vram property

From: suijingfeng <suijingfeng@...ngson.cn>

The LS7A1000 bridge chip is equipped with a dedicated video memory
which is typically 64MB or more. This patch add has_dedicated_vram
property in the display controller device node to reflict this.
