regulator: introduce min_dropout_uV
Many voltage Regulators need a input voltage that is higher than the output voltage. Allow to specify a minimum dropout voltage which will be used later to find the best input voltage for regulators. [Changed uv to uV for consistency and legibility -- broonie] Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
