Honda DBC cleanup

[Shane Smiskol]

• See if LAT_ACCEL under KINEMATICS on 145 is also available on 148 for cars using 145. The LAT_ACCEL signal is defined in the same location in the message
• Fix duplicate gear signals defined
• A lot of these messages are common in bosch vehicles, possible unify:
  • DOORS_STATUS
  • STANDSTILL
  • GEARBOX
  • GAS_PEDAL_2

I believe that both kinematics messages are the same and can have the same signal definitions. Verified with an ILX last night which uses 145. But I don't believe that this car has a 148 message, only 145
