[PATCH rtw-next 7/7] wifi: rtw89: debug: add BB diagnose

[Ping-Ke Shih <pkshih@realtek.com>]

From: Kuan-Chung Chen <damon.chen@realtek.com>

Add BB diagnostic to track potential abnormal conditions. Currently,
five diagnostic metrics are monitored: 1) Hang detection monitors
consecutive absence of TX and RX activity. 2) PD maximum triggers
when PD stays at its maximum threshold for a period. 3) No RX
occurs when no CCA activity is detected over multiple consecutive
cycles. 4) High FA indicates a high false alarm ratio, reflecting
severe environmental interference. 5) EDCCA alerts when high EDCCA
ratio, signaling a potential TX hang.

These metrics are exposed via debugfs diag_bb.

Output:

  [PHY 0]
  Diag bitmap = 0x0
  Event{Hang, PD MAX, No RX, High FA, High EDCCA Ratio} = {0, 0, 0, 0, 0}
  consecutive_no_tx_cnt=0, consecutive_no_rx_cnt=0
