drm/vmwgfx: Remove a few unused functions

Browse Source 
I noticed that there is a prototype for vmw_fifo_ping_host_locked() but
no function. Then I looked further and noticed more functions which are
not used anymore or functions protoypes which remained after the
function was removed.

Remove unused function (prototypes).
