mb/system76/lemp9: update power limits 

Tested on lemp9, power limits are adjusted from the previously low
values to the values the thermal system can handle. This was
determined by increasing the values and running the system at 100%
CPU utilization until thermal throttling occured and the chassis
temperature became uncomfortable.
