This issue have been found in mx53_smd(ENGR00163704), and found in sabresd
if accessing pfuze while system reboot or reset, I2C bus will be blocked
even if reboot,then pfuze will be failed to be probed, all device driver
which use pfuze regulator will be impacted. In u-boot, we can check the
SDA line low or high, if low, generate SCL and STOP signal to tell I2C
device release I2C bus. Please check ENGR00163704
