wifi: rtw88: Extend rtw_debugfs_get_tx_pwr_tbl() for RTL8814AU 

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

commit c374281f828545b3698cf936b584249c2f9e40c5
Author: Bitterblue Smith <rtl8821cerfe2@gmail.com>
Date:   Tue Feb 18 01:32:49 2025 +0200

    wifi: rtw88: Extend rtw_debugfs_get_tx_pwr_tbl() for RTL8814AU
    
    Make it print the TX power details for all RF paths, not just A and B,
    and for all the rates supported by the chip, not just 1SS and 2SS
    rates.
    
    Also skip the RF paths and rates not supported by the chip.
