regulator: of: Added a property to indicate bypass mode support

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Added a property to indicate if the regulator supports bypass mode.
Also modified of_get_regulation_constraints() to check for that
property and set appropriate constraints.
