Subject: [PATCH v2 14/34] ARM: tegra: colibri_t30: add i2c-thermtrip

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Add i2c-thermtrip which would set the DEV_OFF bit in the DCDC control
register of the TPS65911 PMIC.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Changes in v2:
- When running some more tests I realized that the reg-addr should
  really be 0x3f. Fix this.
