[U-Boot] [PATCH v6 13/21] SabreSD: Enable DM_I2C and DM_PMIC

[Jagan Teki <jagan@openedev.com>]

From: Jagan Teki <jagan@amarulasolutions.com>

(1) Enable
    DM_I2C
    DM_PMIC
    DM_PMIC_PFUZE100
(2) Removed
    setup_i2c
    power_init_board

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
Valid chip addresses: 08 48
=> i2c md 08 0x0 0x20
0000: 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10    ................
