wifi: rtw89: 8852c: add quirk to set PCI BER for certain platforms
Increase PCI BER (bit error rate) count depth setting which could increase PHY circuit fault tolerance and improve compatibility. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://msgid.link/20240329015251.22762-4-pkshih@realtek.com
