Mark function ast_bo_unref() as static because it is not used outside
file ast_main.c and remove unused function ast_get_max_dclk() in
ast_main.c.
This eliminates the following warning in drm/ast/ast_main.c:
drivers/gpu/drm/ast/ast_main.c:192:10: warning: no previous prototype
for ?ast_get_max_dclk? [-Wmissing-prototypes]
drivers/gpu/drm/ast/ast_main.c:452:6: warning: no previous prototype for
?ast_bo_unref? [-Wmissing-prototypes]
