WINCE 6 SD Card driver build error, PBInitEnv.bat

In AU1200 BSP, build SD Card driver has the following error!
There is no SDbus.lib.
So remove SD Card driver.
In platform.bib we want to remove BSP_SDHC_AU1X,
and it is defined in PBInitEnv.bat.

But PBInitEnv.bat is created by system.
When u setup catalog item. It will write variables to pbinitenv.bat.
