ath10k: add log level configuration for fw_dbglog
Introduce an optional log level configuration for the existing debugfs fw_dbglog file. It
allows users to configure the desired log level for firmware dbglog messages.
To configure log level as WARN:
echo 0xffffffff 2 > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog
The values are:
VERBOSE 0
INFO 1
WARN 2
ERR 3
