[PATCH -next] drm/sun4i: Make some symbols static

[Yue Haibing <yuehaibing@huawei.com>]

From: YueHaibing <yuehaibing@huawei.com>

Fix sparse warnings:

drivers/gpu/drm/sun4i/sun8i_tcon_top.c:271:36: warning: symbol 'sun8i_r40_tcon_top_quirks' was not declared. Should it be static?
drivers/gpu/drm/sun4i/sun8i_tcon_top.c:276:36: warning: symbol 'sun50i_h6_tcon_top_quirks' was not declared. Should it be static?
drivers/gpu/drm/sun4i/sun4i_tcon.c:239:6: warning: symbol 'sun4i_tcon_set_mux' was not declared. Should it be static?
