iwlwifi: runtime: sync FW and host clocks for logs
For sync we send a marker cmd every <defined throughout debugfs> seconds. The trigger for getting gp2 clock values from the FW is set by writing to debugfs a periodic time in seconds, if value zero is written, only one request would be sent and the timer would be canceled. Also added a small infrastructure for debugfs runtime code. Signed-off-by: Mordechay Goodstein <mordechay.goodstein@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
