[PATCH rtw-next 01/13] wifi: rtw89: debug: Wi-Fi 7 show count of SER L0 simulation

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

From: Zong-Zhe Yang <kevin_yang@realtek.com>

Wi-Fi 7 has dedicated HW register to count SER L0 simulation, i.e.
manually triggered by users. Show count of it in dbgfs ser_counters.
