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.
