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 <aksha...@samsung.com>

Changes since v5:
- Changed 'pirntf' to 'puts'.
- Added 'return -1' in case of erroneous tmu_state.
