imx:mx6sxsabresd fix pfuz probe failed
The PFUZ probe failed with the following msg:
" wait_for_sr_state: failed sr=81 cr=a0 state=2020
i2c_init_transfer: failed for chip 0x8 retry=0
wait_for_sr_state: failed sr=81 cr=a0 state=2020
i2c_init_transfer: failed for chip 0x8 retry=1
wait_for_sr_state: failed sr=81 cr=a0 state=2020
i2c_init_transfer: failed for chip 0x8 retry=2
i2c_init_transfer: give up i2c_regs=021a0000
Can't find PMIC:PFUZE100 "
board_early_init_f is too early to call i2c related setting, because
init_func_i2c is called after board_early_init_f being invoked. Thus
move setup_i2c into board_init.
Also PFUZ is connected to I2C bus 0, so change "1" -> "0".
Using this patch PFUZ can be correctly probed:
"PMIC: PFUZE100 ID=0x11"
