qcacld-3.0: Add support for gpio based strobe to capture tsf

Browse Source 
Add configuration for gpio pin used to send strobe to wlan hw.

The host driver will latch the current time and toggle the gpio
to generate a strobe to wlan hw.

The tsf will be latched on detecting the strobe and it will be
made available in a register for sw access.
The wlan fw will read this tsf and report it to driver using tsf event.
