Jonathan Bakker cfd24b14eb regulator: wm8994: Add an off-on delay for WM8994 variant 
[ Upstream commit 92d96b6037 ]

As per Table 130 of the wm8994 datasheet at [1], there is an off-on
delay for LDO1 and LDO2.  In the wm8958 datasheet [2], I could not
find any reference to it.  I could not find a wm1811 datasheet to
double-check there, but as no one has complained presumably it works
without it.

This solves the issue on Samsung Aries boards with a wm8994 where
register writes fail when the device is powered off and back-on
quickly.
