soc/intel/apollolake: Update PL1 value in RAPL MMIO register
Due to an incorrect value set for the power limit PL1, the
system is not able to leverage full TDP capacity. FSP code
sets the PL1 value as 6W in RAPL MMIO register based on
fused soc tdp value. This RAPL MMIO register is a physically
separate instance from RAPL MSR register. This patch sets
PL1 value to 15W in RAPL MMIO register.
BUG=chrome-os-partner:56524
TEST=Built, booted on reef and verifed the package power
with heavy workload.
