syncpt cmdbuf specific functions are only for the sync functionality of nvgpu and donot belong to fifo. construct files syncpt_cmdbuf_gk20a.h and syncpt_cmdbuf_gk20a.c under common/sync to contain the syncpt specific cmdbuf functions for arch gk20a. The word 'fifo' is also removed from the name of these functions.
