cnss2: Add support to handle SOL GPIOs

Telusuri Sumber 
The side-band SOL (Sign-Of-Life) GPIOs are introduced to help make
RDDM more reliable so that device dump can be copied correctly. When
device SOL GPIO is triggered from device, it means there is watchdog
reset happened in device and driver should expect RDDM to happen.
When host SOL GPIO is triggered from host, it will result watchdog
reset as well as PCIe controller reset in device which should try to
enter RDDM always. This commit also adds debug hooks for the GPIOs.
