scsi: ufs: Make the TC G210 driver dependent on CONFIG_OF

The TC G210 driver only supports devices declared in the device tree.
Hence make this driver dependent on CONFIG_OF. This patch fixes the
following compiler error:

drivers/ufs/host/tc-dwc-g210-pltfrm.c:36:34: error: ‘tc_dwc_g210_pltfm_match’ defined but not used [-Werror=unused-const-variable=]
   36 | static const struct of_device_id tc_dwc_g210_pltfm_match[] = {
      |
