regulator: Add over current protection (OCP) support
Some regulators can automatically shut down when they detect an over current event. Add an op (set_over_current_protection) and a DT property + constraint to support this capability. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>
