Description: Handle trigger page support after reset. Prior to IOC reset, if firmware is not supporting trigger pages and after reset if driver sees the firmware started supporting trigger pages. (In case of a reset after firmware upgrade) then the driver should handle this by writing the already available trigger data from the driver’s internal data structure to the corresponding trigger pages NVRAM region and also update Trigger flags in Trigger Page-0 NVRAM region accordingly. Implementation: Add ioc->supports_trigger_pages, this feature supported flag is used to determine whether the pages needs update or not. And also this feature supporting flag needs to be updated for every reset as it is possible that FW won’t support trigger pages before reset and start supporting after reset or vice versa.
