A single DM-based driver should be able to support some feature for several PMIC variants where the interface is the same. For example, all PMIC variants use the same register bit to trigger poweroff. However, currently only definitions for a single PMIC are available at a time. This requires drivers to use #ifdefs and different indentifiers for each variant they support. Let's simplify this by making register definitions for all variants available from the header. Then no preprocessor conditions are needed; the driver can use the register definition from any variant that supports the relevant feature. An exception is the GPIO-related definitions, which do not use unique identifiers. So for now, keep them like before. They will be cleaned up along with the GPIO driver.
