Ariel: stream driver

建立stream driver需注意之事項，以527 為例
1.在project下建立自己的driver folder，ex: ARIEL
並修改dirs檔案，加入自己driver的名字

BARCODE \
ARIEL \

接著在driver folder內需建立.c、.def、source和makefile ，ex:ariel.c、ariel.def
(.def、source需修改，可以複製其他driver的來做，makefile亦可複製其他driver來用)

2.修改source檔
!if 0
File: sources

4.修改platform.bib檔
加入
