From: Jagan Teki <jagan at amarulasolutions.com>

Enable DM_I2C, DM_PMIC and DM_PMIC_PFUZE100 for dt
supported sabresd config boards:
- imx6q_sabresd_defconfig
- imx6qp_sabresd_defconfig

I2C Log:
--------
=> i2c bus
Bus 0:  i2c at 021a0000
Bus 1:  i2c at 021a4000
   08: pfuze100 at 08, offset len 1, flags 0
Bus 2:  i2c at 021a8000
=> i2c dev 1
Setting bus to 1
=> i2c speed 100000
Setting bus speed to 100000 Hz
=> i2c probe
