ARM: ux500: regulators: Add mask for configuration
There is already before a register mask in the regulator driver to allow some bits of a register to be initialized. The register value is defined in the board configuration. This patch puts a mask in the board configuration to specify which bits should actually be altered. The purpose with this patch is to avoid future mistakes when updating the allowed bits in the regulator driver.
