regulator: virtual: warn against production use

    regulator: virtual: warn against production use

    This driver is only meant for debugging and testing.  Currently, it's
    not possible to use it without patching the kernel since it requires
    platform data, but we'll be adding devicetree support, so add a loud
    warning to make it clear that it's still only meant for debugging and
    testing.
