ath11k: add support of firmware logging for WCN6855
Host enables WMI firmware logging feature via QMI message.
Host receives firmware logging messages on WMI_DIAG_EVENTID, then
sends logging messages to user space via event tracing infrastructure.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
