The address end of working buffer can't be calculated directly with buffer
size in kernel for some special architecture. Adding new extend vsi_ex to
calculate the address end in firmware.
Adding capability to separate extend and non extend driver for different
platform.
At last, hardware can parse the syntax to get nal information in firmware
for extend architecture, needn't to parse it again in kernel.
