添加开发板至PHYTIUM BSP

注:BSP已支持E2000Q_DEMO,E2000D_DEMO,PHYTIUMPI开发板，若需填加系列其他开发板，请按以下步骤进行

以cus_demo_board(E2000D系列)开发板为例进行说明

在bsp/phytium/board下创建cus_demo_board文件夹
```
$ cd bsp/phytium/board
$ cd mkdir cus_demo_board
```
创建文件fio_mux.c和fio_mux.h，添加引脚复用函数
```
$ touch fio_mux.c
$ touch fio_mux.c
```
可参考bsp/phytium/standalone/board/e2000d_demo 目录下的fio_mux.c和fio_mux.h文件，示例基本框架已完成，只需填充函数
在bsp/phytium/board 目录下SConscript文件中添加如下内容，将fio_mux.c和fio_mux.h文件加入编译
