intel/kunimitsu: Update the PL1 value as TDP
Currently, the Power Limit 1 (PL1) value is 6W which is
low for high performance KPIs. This patch updates PL1
value as TDP. SKL-U has 15W TDP.
BRANCH=None
BUG=None
TEST=Built and boot on kunimitsu. Check for the PL1 value over
sysfs interface
"/sys/class/powercap/intel-rapl:0/constraint_0_power_limit_uw".
Load the system with Aquarium 1000 Fish, average FPS should be
meeting target 60 with this change.
