hwmon: (peci/dimmtemp) Bump timeout

The PECI CPU sensors are available as soon as the CPU is powered,
however the PECI DIMM sensors are available after DRAM has been
trained and thresholds have been written by host firmware.

The default timeout of 30 seconds isn't enough for modern multisocket
platforms utilizing DDR5 memory to bring up the memory and enable PECI
sensor data.
Bump the default timeout to 10 minutes in case the system starts
without cached DDR5 training data.
