[DSP]Added duplicate functions for buffer lock and unlock.

This is required temporarily as there is no other way to
get the core index.dce_buf_lock and unlock functions expects
MmRpcHandle  and now as there are separate handles for DSP
and IPU, to avoid modifying these APIs, duplicate functions
have been created coreIndex is hardcoded.

Added prototypes of dsp specific lock and unlock functions
in libdce.h
