The actual regulator helpers wrongly assume that the regulator control is always performed using single bits, using in the regulator_desc struct only two parameters *_reg and *_mask defining register and mask for control. This patch extends this struct and introduces the helpers to take into account devices where control is performed using multiple bits and specific multi-bit values are used for enabling/disabling/bypassing the regulator.

So we can calculate max_uV for each linear range in regulator core rather than set the max_uV field in drivers.

Provide regulator_{map,list}_voltage_linear_range() allowing these regulators to use generic code. To do so a table of regulator_linear_range structs needs to be pointed to from the descriptor. This was inspired by similar code included in a driver submission from Chao Xie and Yi Zhang at Marvell. Signed-off-by: Mark Brown <broonie@linaro.org>
