Debarshi Dutta ebe6fa7fac gpu: nvgpu: move syncpt specific cmdbuf methods to common/sync/
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.

Jira NVGPU-1308
