mushu: Bring up F75303 temp sensor

BRANCH=None
BUG=b:158676970
TEST=Force fan off/run heavy workload
Use temps command in ec console, see temp
> temps
CHARGER             : 318 K = 45 C  64%
5V                  : 316 K = 43 C  61%
GPU                 : 343 K = 70 C  100%
F75303_Local        : 331 K = 58 C
F75303_GPU          : 340 K = 67 C
F75303_GPU_Power    : 332 K = 59 C
