regulator: bd718x7: Add enable times

stable inclusion
from stable-5.10.9
commit 36afeaad76711ff80c2dc57450ad9c5f2f382b41
bugzilla: 47457

--------------------------------

[ Upstream commit 3b66e4a8 ]

Use the typical startup times from the data sheet so boards get a
reasonable default. Not setting any enable time can lead to board hangs
when e.g. clocks are enabled too soon afterwards.

This fixes gpu power domain resume on the Librem 5.

[Moved #defines into driver, seems to be general agreement and avoids any
cross tree issues -- broonie]
