scsi: ips: fix firmware timestamps for 32-bit
do_gettimeofday() is deprecated since it will stop working in 2038 on 32-bit platforms, leading to incorrect times passed to the firmware. On 64-bit platforms the current code appears to be fine, as the calculation passes an 8-bit century number into the firmware that can represent times long in the future (possibly until 25599). Using ktime_get_real_seconds() to get a 64-bit seconds value and time64_to_tm() to convert it into the firmware format greatly simplifies the ips timekeeping code, makes 32-bit and 64-bit behave the same way here, and gets us closer to removing the deprecated interfaces.
