watchdog: qcom: introduce the device data for IPQ5424 watchdog device 



To retrieve the restart reason from IMEM, certain device specific data
like IMEM compatible to lookup, location of IMEM to read, etc should be
defined. To achieve that, introduce the separate device data for IPQ5424
and add the required details subsequently.
