ath10k: add support to configure pktlog filter

Add support to configure packet log filters (tx, rx, rate control)
via debugfs. To disable htt pktlog events set the filters to 0.

ex:

To enable pktlog for all filters

   echo 0x1f > /sys/kernel/debug/ieee80211/phy*/ath10k/pktlog_filter

To disable pktlog

   echo 0 > /sys/kernel/debug/ieee80211/phy*/ath10k/pktlog_filter
