Subject: [PATCH] wifi: rtw88: Constify some more structs and arrays

These structs and arrays are never modified, so make them const:

rtw_band_2ghz
rtw_band_5ghz
rtw_pci_tx_queue_idx_addr
rtw_pci_ops
rtw_cck_rates
rtw_ofdm_rates
rtw_ht_1s_rates
rtw_ht_2s_rates
rtw_vht_1s_rates
rtw_vht_2s_rates
rtw_rate_section
rtw_rate_size
rtw_sdio_ops
rtw_usb_ops
