sparse warnings: (new ones prefixed by >>)

>> drivers/net/wireless/realtek/rtw88/mac.c:653:5: sparse: sparse:
symbol '__rtw_download_firmware' was not declared. Should it be static?
>> drivers/net/wireless/realtek/rtw88/mac.c:817:5: sparse: sparse:
symbol '__rtw_download_firmware_legacy' was not declared. Should it be
static?
