Subject: [PATCH] regulator: lp872x: Don't set constraints within the regulator driver

From: Mark Brown <broonie@...aro.org>

Regulator drivers should not be specifying constraints since the valid
configurations depend on how the device is used in a given system, there
is no way to know if a configuration is safe for a given board.
