Add generic TMU support alongwith i2c sensors in dtt command to enable temperature reading in cases where TMU is present instead of i2c sensors.
Signed-off-by: Akshay Saraswat akshay.s@samsung.com --- Changes since v5: - Changed 'pirntf' to 'puts'. - Added 'return -1' in case of erroneous tmu_state.
