Subject: [PATCH 3/4] Bluetooth: hci_qca: mark OF related data as maybe unused

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

  drivers/bluetooth/hci_qca.c:1869:37: error: ‘qca_soc_data_wcn6750’ defined but not used [-Werror=unused-const-variable=]
  drivers/bluetooth/hci_qca.c:1853:37: error: ‘qca_soc_data_wcn3998’ defined but not used [-Werror=unused-const-variable=]
  drivers/bluetooth/hci_qca.c:1841:37: error: ‘qca_soc_data_wcn3991’ defined but not used [-Werror=unused-const-variable=]
  drivers/bluetooth/hci_qca.c:1830:37: error: ‘qca_soc_data_wcn3990’ defined but not used [-Werror=unused-const-variable=]
