PM / sleep: Increase default DPM watchdog timeout to 120
Recently we have a new report that, the harddisk can not resume on time due to firmware issues, and got a kernel panic because of DPM watchdog timeout. So adjust the default timeout from 60 to 120 to survive on this platform, and make DPM_WATCHDOG depending on EXPERT.
