Add t6cal console command to set/print TMP006 calibration
Note that radix must be specified as an integer, because we don't have
floating-point parsing. So to set the first sensor's S0 to 3.600e-14,
do:
t6cal 0 S0 3600
BUG=chrome-os-partner:14955
BRANCH=link
TEST=manual
From EC console,
t6cal 0 s0 3500
t6cal 1 b0 -3000
t6cal 1 b1 -5600
t6cal 2 b2 4700
t6cal
The final t6cal should show the changes from the previous commands
