wifi: rtw88: Constify some more structs and arrays 

JIRA: https://issues.redhat.com/browse/RHEL-89168

commit e66f3b5c7535bb508e9c561a047b32de4ddc1cda
Author: Bitterblue Smith <rtl8821cerfe2@gmail.com>
Date:   Tue Feb 4 20:40:22 2025 +0200

    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
