Mark functions ast_set_sync_reg(), ast_set_dac_reg(),
ast_set_start_address_crt1(), ast_crtc_init(), ast_encoder_init(),
ast_connector_init(), ast_cursor_init(), ast_cursor_fini(),
ast_show_cursor() and ast_hide_cursor() as static in drm/ast/ast_mode.c
because they are not used outside this file.

This eliminates the following warning in drm/ast/ast_mode.c:

‘ast_set_sync_reg’ [-Wmissing-prototypes]
