drivers: regulator: fixed: add u-boot, off-on-delay-us
Add u-boot,off-on-delay-us for fixed regulator. Depends on board design, the gpio regulator sometimes connects with a big capacitance. When need to off, then on the regulator, if there is no enough delay, the voltage does not drop to 0, so introduce this property to handle such case.
