Add t6cal console command to set/print TMP006 calibration

Browse Source 
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
