The working buffer address start and end are calculated in kernel
side currently, the address end can't be calculated if the driver
only getting the address file handle, not the real physical address.
Need to send the extended vsi to firmware to calculate the address
end.

Re-construct some interface and add configuration to support extend
and non extend driver at the same time. Needn't to parse nal info for
extended architecture.
