soc/intel/common: Do not trigger crashlog on all resets by default

Crashlog has error records and PMC reset records two parts. When we
send ipc cmd "PMC_IPC_CMD_ID_CRASHLOG_ON_RESET", PMC reset record is
enabled. At each warm/cold/global reset, crashlog would be triggered.
The cause of this crash would be "TRIGGER_ON_ALL_RESETS", it is used to
catch unknown reset reason. At the same time, we would see [Hardware
Error] in the kernel log.

If we default enable TRIGGER_ON_ALL_RESETS, we would have too many false
alarm. Now we disable PMC reset records part by default. And we could
enable it when we need it for the debug purpose.

The generated bert dump is under /var/spool/crash/, we could check this
path to verify this CONFIG disable/enable status.

BUG=b:202737385
TEST=No new bert dump after a warm reset.
