Subject: [PATCH v2 11/39] ASoC: rockchip: mark OF related data as maybe unused

The driver can be compile tested with !CONFIG_OF making certain data
unused:

  sound/soc/rockchip/rockchip_i2s.c:569:34: warning: ‘rockchip_i2s_match’ defined but not used [-Wunused-const-variable=]
  sound/soc/rockchip/rockchip_pdm.c:463:34: warning: ‘rockchip_pdm_match’ defined but not used [-Wunused-const-variable=]
  sound/soc/rockchip/rockchip_spdif.c:44:34: warning: ‘rk_spdif_match’ defined but not used [-Wunused-const-variable=]
